Is Yong Heng tapped 1/8NPT?1/8BSP? Or M10?.ISO longer fill whip for garage setup

I have so many whips, fittings, adapters, etc. I couldn't tell you which is on which. It is a big hassle in my opinion. Same with gauges, NPT? Bnpt? needs a delrin washer underneath? Teflon tape, paste? loctite? super glue? on and on, into the darkness.......

The threads on the compressor outlet are M10x1. What you use on the other end is up to you. Most of the Chinese filters are also M10x1 if that helps. https://www.aliexpress.com/item/32853214021.html?spm=a2g0s.9042311.0.0.27424c4dCjIWDS

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!

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. 

check out a Hydraulic supply shop. Their stuff will handle the hpa. Only trouble is the lines are larger than micro and take more to fill them.
