Introducing the new JRP Universal Oil Filter Sandwich Plate, a product born from years of experience and customer feedback. After selling standard sandwich plates for sensor installations, we’ve learned what makes a great plate and where most designs fall short. With this knowledge in hand, our head engineer set out to create something we could truly be proud of, delivering a product that combines innovative design, superior materials, and unmatched quality.
Important Notice:
These sandwich plates are designed specifically for use with JRP gauge products OR for applications requiring 1/8 BSP threaded fittings. All our temp & pressure sensors utilize 1/8 PT threads, which are compatible with both 1/8 NPT and 1/8 BSP ports. As a result, the ports on these sandwich plates are threaded for 1/8 BSP.
If you are using gauges or sensors from other brands that rely on 1/8 NPT fittings, these sandwich plates may not be suitable for your setup. Most other aftermarket gauges and sensors are designed with 1/8 NPT threads, and those will not align with the threading of these plates.
However, if you are using JRP sensors and gauges, these plates are an ideal match. With their A+ quality construction, they are designed to seamlessly integrate with JRP products. For more details, check out the information below.
Why Choose JRP’s Oil Filter Sandwich Plate?
Most oil filter sandwich plates on the market are functional but basic. While they get the job done, there’s clear room for improvement especially in the seal materials. Many standard plates use basic rubber seals, which lack the durability and reliability needed for high-performance applications. That’s why JRP has raised the bar by incorporating HNBR seals into our sandwich plates.
Our seals are easy to recognize by their distinctive green colour, but it’s what’s under the surface that truly sets them apart. HNBR (Hydrogenated Nitrile Butadiene Rubber) is vastly superior to standard rubber in terms of temperature resistance, chemical stability, and longevity. This innovation reduces the risk of leaks and ensures your engine stays protected, even in extreme conditions. For more details on why HNBR seals are a game-changer, check out the information below.
Engineered for Reliability and Quality
A failed seal on a sandwich plate can be more than just an inconvenience it can lead to significant oil loss and pose a real risk to your engine. At JRP, we’re all about doing things better. That’s why we’ve paired our HNBR seals with a sleek, precision-engineered design. Our plates are crafted with extreme-quality CNC machining, ensuring perfect threads and exceptional durability.
We’ve positioned our plates to compete with top-tier brands like Mishimoto, known for their excellent products. The key difference? JRP delivers this level of quality at a more reasonable price. By leveraging our well-equipped factory and selling directly to customers, we cut out the middleman’s markup, making premium products accessible without compromising on quality.
Stainless Steel Adapter Bolt *Sold Separately*
To ensure flexibility and reduce waste, we’ve designed our sandwich plates to be sold separately from the adapter bolts. While many competitors bundle their plates with cheap alloy fittings—resulting in unnecessary extras and lower durability we provide high-quality stainless steel adapter bolts as a separate purchase. This approach allows you to select only the adapter bolt that fits your engine, reducing waste and ensuring a longer-lasting, more reliable setup.
When ordering your sandwich plate, be sure to check the information below to determine the correct stainless steel adapter bolt for your engine. With the right combination, you’ll have everything needed for a simplified, leak-free installation of your oil temperature and pressure sensors.
Will This Fit My Car?
In most cases these cannot be used on Diesels. It’s because the actual size of the oil filter is larger than the plates. The adapter bolts required on Diesels are also larger, M24x1.5 for example.
The best way to find out if these plates can be used is by cross checking with Ryco. Simply put into Google your Ryco oil filter part number, so a search like “Ryco Z386” for example, then click on the first link to the Ryco page for that oil filter and the adapter bolt size will be listed on the Ryco page for your filter.
If the Ryco website lists any of the below sizes for your oil filter thread then you can use our JRP sandwich plates, if they show something like M24x1.5, M14x1.5 etc you won’t be able to use the sandwich plates and will need to use an alternative method for installing your Oil Temp / Oil Pressure sensors. Such as removing the factory Oil Pressure Sensor, getting lines made up at Pirtek to be able to screw your old Oil Pressure sensor into the line, along with our 1/8 PT threaded Temp & Pressure sensors supplied in our gauge kits.
Note, there are some Nissan Patrol TD42’s that can use these plates, if you are the owner of a Patrol, you could have a model of the TD42 which can use these plates, so look up your Ryco oil filter, as we have seen a decent amount of these motors that take oil filters using the 3/4-16-UNF & 3/4 x 16 threads and you can make the install of an oil pressure sensor a lot simpler using one of these sandwich plates.
Adapter Bolt Sizes Available
M18 x 1.5
3/4-16-UNF & 3/4 x 16
13/16-16-UNF
M20 x 1.5
M22 x 1.5
Why HNBR Seals are Superior to Standard Rubber Seals in Oil Filter Sandwich Plates
When designing an oil filter sandwich plate, the choice of seal material is critical to ensuring long-term performance, reliability, and durability under demanding conditions. While standard rubber seals are commonly used, they come with limitations in terms of temperature tolerance, chemical resistance, and mechanical properties. By opting for hydrogenated Nitrile (HNBR) seals, significant advantages are achieved:
1. Exceptional Temperature Resistance
- Standard Rubber Seals: Typical rubber seals often degrade or lose elasticity when exposed to high temperatures, such as those found in engine oil systems. This leads to potential leaks or failures.
- HNBR Seals: HNBR is specifically engineered to withstand extreme temperatures ranging from -40°C (-40°F) to 150°C (302°F) and higher. This makes it highly reliable in the fluctuating thermal environment of an engine, where oil can become extremely hot during operation.
2. Superior Chemical Resistance
- Standard Rubber Seals: Over time, rubber seals can break down when exposed to oil additives, fuel, and other automotive chemicals. This results in swelling, cracking, or a loss of sealing integrity.
- HNBR Seals: HNBR offers exceptional resistance to a wide range of automotive fluids, including engine oils, transmission fluids, and coolants. It also resists degradation from modern synthetic oils and aggressive additives, ensuring the seal remains intact and functional over the long term.
3. Improved Mechanical Properties
- Standard Rubber Seals: Regular rubber materials tend to lose their flexibility and become brittle after prolonged exposure to heat and pressure. This can result in leaks as the seal fails to maintain proper contact surfaces.
- HNBR Seals: HNBR is known for its excellent mechanical strength, tear resistance, and elasticity. Even under high-pressure oil systems, the material retains its shape and provides a consistent, leak-free seal.
4. Enhanced Durability and Longevity
- Standard Rubber Seals: The wear and tear of standard rubber seals often lead to frequent replacements, increasing maintenance needs and costs.
- HNBR Seals: The hydrogenation process in HNBR enhances its durability, allowing it to withstand prolonged exposure to harsh conditions without significant wear. This longevity reduces the need for frequent replacements and ensures a reliable, long-term seal.
5. Compatibility with High-Performance Applications
For enthusiasts and customers who install aftermarket sensors (such as oil temperature and oil pressure sensors), the oil filter sandwich plate operates in an environment where precision and reliability are critical. HNBR seals are ideal for these high-performance scenarios because they maintain their properties under stress and ensure accurate sensor readings by preventing leaks or pressure fluctuations.
Conclusion
By using HNBR seals in our oil filter sandwich plates, we provide customers with a product that offers superior performance and reliability compared to those using standard rubber seals. These seals ensure a leak-free connection, even under extreme conditions, while enhancing the longevity of the product. This thoughtful design choice underscores JRP’s commitment to quality and customer satisfaction, along with making this product a stand out when compared to other sandwich plates on the market.
