Key Features & Benefits – Epman oil pressure oil temperature sandwich adapter 1/8 port
The Epman oil pressure oil temperature sandwich adapter 1/8 port is a sandwich plate that mounts between the engine and the factory oil filter, adding practical connection points for sensors and an oil-cooler circuit.
It uses 1/8 NPT sensor ports and a double O-ring seal. The design is compatible with center-thread solutions for 3/4-16 UNF, M18x1.5, M20x1.5, M22x1.5 oil filter mounts.
When is this useful?
It is useful when you want a clean location for oil pressure or oil temperature senders, or when you are adding oil-cooler plumbing and prefer compact connections around the oil filter area.

Selection & installation tips
- Center thread: confirm your oil filter mount thread (3/4-16 UNF, M18x1.5, M20x1.5, M22x1.5) and match the center-thread solution to your setup.
- Port thread: make sure your senders and plugs are 1/8 NPT and use the correct sealing interface.
- Clearance: check space after installation around the oil filter and nearby parts (subframe, exhaust, lines).
- O-rings: clean mating faces, seat O-rings evenly, and avoid pinching them during tightening.
- Leak check: inspect the sealing face and ports after first start, then re-check after a short heat cycle.
Before final assembly, verify the center thread, 1/8 NPT sender connections, and available clearance on your engine, then compare them with the technical specs listed above for a correct match.
