Description
1/8" BSPT Oil Pressure Sensor Tee to NPT Adapter
Add an oil pressure gauge, turbo feed line, or auxiliary sensor without sacrificing your factory oil pressure sender. This precision-machined stainless steel tee adapter converts a single 1/8" BSPT port into dual NPT outputs — giving you the flexibility to monitor and feed from one location.
Key Features
-
304 Stainless Steel Construction: CNC-machined from solid billet stainless steel for superior strength and corrosion resistance in high-temperature engine bay environments.
-
Dual Port Design: One BSPT male inlet converts to two NPT female outlets — run your factory sensor and an aftermarket gauge or turbo feed simultaneously.
-
Precision Thread Conversion: Properly converts 1/8" BSPT (tapered) to 1/8" NPT threads — two different standards that are NOT directly compatible without an adapter like this one.
-
Compact & Low-Profile: Minimal footprint fits in tight engine bay spaces where larger tee fittings won't clear.
-
Universal Application: Compatible with any engine using a 1/8" BSPT oil pressure port — import, domestic, diesel, and gas applications.

Frequently Asked Questions
Q: What is this adapter used for?
A: This tee adapter allows you to install both an oil pressure sensor (or turbo feed line) and a pressure gauge sender simultaneously from a single BSPT port. It converts 1/8" BSPT male threads to NPT female ports.
Q: What vehicles does this fit?
A: It fits any engine with a 1/8" BSPT oil pressure port — common on many import and domestic engines. Perfect for adding an aftermarket oil pressure gauge or turbo oil feed line alongside your factory sensor.
Q: Is this made of stainless steel?
A: Yes — CNC-machined from 304 stainless steel for maximum corrosion resistance. It won't rust or degrade even in high-temperature engine bay environments.
Q: Will this leak under high pressure?
A: No — when properly installed with thread sealant on the BSPT tapered threads, this tee handles oil pressures far exceeding normal engine operating ranges. The NPT ports also seal with standard thread tape or sealant.
Q: What thread types are involved?
A: The male side is 1/8" BSPT (British Standard Pipe Taper). The female ports are 1/8" NPT (National Pipe Taper). Note: BSPT and NPT are different thread standards — this adapter properly converts between them.
