TracTuff 1/8" BSPT Adapter - Aluminum


All Honda's and many imports use a 1/8" BSPT (British Standard Pipe Thread) female port to install the factory oil pressure sending unit and these rather uncommon threads make it hard to add accessories without damaging the fine threads in the block. In 2010 I sought out to make a fitting that had the correct thread and taper that converted to common -3 and -4 male flare connections as well as have enough real-estate to add a port or two for the FACTORY OIL PRESSURE SENSOR. The solution is unique and clean! Getting oil to your turbo, aftermarket pressure gauge, and/ or accessory without damaging the OEM oil pressure port threads. 

One end of the adapter has a OEM spec (thread size, length, and taper) male 1/8" BSPT thread and the other is either a -3 or -4 AN male; eliminating the need to purchase an additional fitting that screws into a BSPT adapter as well eliminates another place for a possible oil leak! Offered with or without a port on the body to install the factory oil pressure sending unit or any other small accessory that threads into a female 1/8" BSPT or 1/8" NPT port. No more cramming 1/8" NPT adapters into the block, where they will ruin threads, leak, get over tightened and potentially split/ break the casting! 

I do NOT recommend adding aftermarket oil pressure/ temperature sensors to this adapter! I have never heard of one failing but it is a major concern and an overall bad idea to add anything larger or heavier than the OEM pressure switch. If you are installing the OEM pressure switch and need an additional accessory, I highly recommend looking at my Remote Fluid Log or Remote Pressure Sensor Mount. If you are not reinstalling the OEM pressure switch, you can use this adapter or the more compact stainless steel BSPT -4 adapter to send oil to something remotely.

Weight, heat and vibration wreak havoc on parts... do them and yourself a favor by not having an oil fire! Its the smartest way to add multiple things that need an oil pressure or temp source.

If you happen to order either with different female ports (threads) the BSPT will be identified by a small dimple as shown below.
