Eaglebeak THANK YOU!!👊

This is EXACTLY what I'm looking for! I'm pumped!! It's even wrapped in the protective wire which is in my opinion good for the microbore as you know how lines can get unintentionally kinked!😲

2 questions for ya now that I have the correct spit to order from......

1: What is the average shipping duration to the states.....average....i know we probably don't live in the same state.

2: Is there a way I can rate your help/reliability on this platform? I feel you should get some credit for saving me from ripping my face off......Hahaha!😤

LMAO!! That is EXACTLY how I felt and wanted to avoid wasting energy and $$ trying to figure out what the hell was what. I did a search on pipe threads in America vs. Europe and Asia. NPT is American standard and is TAPERED or CONICAL if you will.....BSP or BSPP is Europe (actually British to my understanding) and M10x1 is Asia? 

Now.....This is my understanding from reading and could not be EXACTLY on point but I know I'm in the ballpark. I did end up using my thread pitch gauges out of my tap & die set on my stock whips that came with the compressor and my gold filter resulting in M10x1 which was a safe bet on the compressor block, I just wanted to confirm before I crossthreaded the damn pump like a tool and then ended up kicking my own ass later on when a leak started or if I ever wanted to change my pump setup location and needed different hoses to accomodate.

Hope this helps you too!!

The answer to question one is I don't know how long it will take to ship to the States as I live in Australia but I bought a 2-metre hose from this supplier and I think it took about 3 weeks. I think that you could probably expect the same or maybe less, over there but there might be a delay because of the Chinese new year or even the Coronavirus. For question two, if you find the information helpful, you can click on the green + button for accuracy. Just for future reference, NPT is a tapered thread and is mainly used by the paintball crowd and is common in the USA. BSPP stands for British standard pipe parallel and is more common in airguns and is used more in the rest of the world. Metric threads are becoming more common everywhere and will probably replace the others eventually, IMO.

As to what thread is used where, it is a crap shoot. I can tell you that the most common thread used in high pressure air is BSPP..........everywhere. That stands for British Standard Pipe (Parallel) as opposed to BSPT (Tapered). British threads use a 55 degree thread form. National Pipe Threads (NPS)(Straight) and NPT)(Tapered) and Metric threads all use a 60 degree form. All straight threads (NPS & BSPP) require a sealing ring or washer. The washer can be at the top or bottom of the thread and can be copper, aluminum, plastic or steel with rubber. The taper, if you care, on both NPT or BSPT is 3/4" per foot. Tapered threads seal on the thread and require a sealing medium like Teflon tape or thread sealant.

The most common size for guns and small, not commercial, compressors is 1/8". Please note that even though the thread form is different between BSP(P)(T) and NP(T)(S), the threads per inch is just slightly different and one can thread into the other with light resistance, 28 TPI and 27 TPI respectively. So be very careful.

Commercial high pressure compressors like the Bauer use both 1/8" and 1/4" fittings again in BSPP. Piping between stages and filters/dryers is heavy wall stainless steel tubing that use ferules for sealing with BSPP compression fittings. These are typically 3/8" and 1/2" BSPP. All connecting tube lines require a bent 360 loop to compensate for thermal expansion and contraction......very important.

So, the question of how to determine what you have is the conundrum. The correct answer is a set of plug and go/no go gauges. However, these are expensive and only some shops will have them. I use my tap and die sets as test gauges when in doubt. You do not need a full set, as good sets are also pricey. For the air gun enthusiast, only 1/8" NPT, 1/8"NPS, 1/8" BSPP, 1/4" NPT, 1/4" NPS, 1/4" BSPP , 1/4" BSPT, M6. M8 and M10 Taps and Dies are required. These are affordable and well worth having.

Another confusing issue is pipe sizing is based on the approximate ID and wall thickness is determined by its Schedule. Consequently, the OD of a pipe thread is much larger than the stated diameter number. This is opposed to tubing which is based on its OD with a separate wall thickness number.
