If you’re installing an aftermarket oil pressure sender to your Small Block 305/350, we have a Chevy/GM Oil Pressure Adapter made specifically for you.

This oil pressure adapter fitting saves installation time and sidesteps the need for drilling or making other major modifications. Simply use the male 1/8-27 NPT thread to attach it to the block.

Along with the 1/8 NPT thread, the Chevy 350 oil pressure sending unit adapter also has (3) Female 1/8-27 NPT threads set up at 45 degrees and 90 degrees. The design gives you extra clearance when you’re installing the sensors. A 1/8-27 NPT Port Plug caps an open port.

You can install an oil temperature or another type of sensor too.

We came up with the idea when we were doing some work on a 305/350 and needed an easier way to install an oil PSI sensor. After testing out a few different designs we came up with this oil pressure sensor adapter.

The fitting is built to be durable and long lasting also. It’s machined from steel with nickel plated zinc. That way it’ll get the job done over the long term and make sure that your sensors are in the right position.

Make this Chevy/GM oil pressure adapter for the Small Block 305/350 part of your custom modifications. If you’re installing an oil PSI, oil temp, or another kind of sensor, you’ll spend less time in the garage and more time on the road.
