Can someone tell me what threads are on the air output port on the aluminum filter? I want to install a male fill nipple to replace the fixed air line. Thanks.
It’s the standard 1/8” bspp used in pcp fittings. You can re use that dowdy washer.
how I was able to find out is I took a fitting off of my hand pump that I knew was all bspp thread, and it threaded right on there smoothly.
Yes you can turn the aluminum block. It is bolted from the bottom, just loosen and turn. Make sure you clean the inside and the pressure valve on top with every oil change. I have attached a photo of what the inside looks like when you do not do routine maintenance.
BSP vs NPT. ... BSPT equivalent is NPT and BSPP's equivalent is NPS. Never swapthreads if it is a high pressure application. NPT/NPS and BSP threads are notcompatible due to the differences in their thread forms, and not just the fact that most sizes have a different pitch.
