Sorry, guys, I found the link but the item is listed as no longer available. https://www.aliexpress.com/item/4000125018554.html?spm=a2g0o.order_list.order_list_main.45.394118026Jnj9A You may be able to use the link to use the algorithm to find other similar sites. That's how I was able to find...

Similar fittings can be made from cheap parts from Ali Express or Flea bay at less than half of what they are asking for that dog's breakfast. The fitting on top is the same as the airtanks plus version and can be quickly changed to a male-female arrangement if need be. It also has a pressure...

Water-cooled reciprocating compressors are similar to internal combustion engines. The tolerances are machined to match the correct clearances at the safe operating temperature range (50c-80c) that the machine is designed to run at. Running an engine too cold will reduce the tolerances and...

The pump that is in your pictures is a definite Yong Heng hardcover version. I have never seen nor heard of a so-called clone that matches the exact plumbing and features of the YH branded unit. The YH pump is itself a clone of the early Davv unit. You didn't mention what parts are missing. I...

M18x1.5 threads aren't a Chinese peculiarity. Almost the whole world is using the metric system now. I own a US-made Luxfer SCBA bottle that has an M18x1.5 thread in its neck because it's made for the Australian market. The type of thread used is irrelevant to its certification by D.O.T. or any...

Your fill bottle has only 3000 psi in it. That is only just over 200BAR. You won't be able to fill anything to a higher pressure than what the doner bottle contains. If you want to fill your gun to 4500 psi you will need to fill your so-called tiger shark to its maximum pressure and from there...

Hand pumps will condense the same amount of moisture as any other compressor or pump considering the same pressure and volume. Hand pumps are more problematic because they don't usually have any sort of separator on the output side. It is feasible to install a very small high-pressure filter in...

I say yee. Now explain where you are going to find a1 thou. drill bit?

The bottle looks like one of the old fiberglass-wrapped models that were used before carbon fiber became the norm. It is 32 years old. It doesn't matter how many times it has been filled or how it has been stored. It may be just fine to use but I would consider it extremely foolhardy to risk...

The answer to your question is in Steve's chart above. A 45-minute SCBA bottle has a liquid or gas (at one atmosphere) capacity of 6.8 litres or about 1.8 US gallons. When compressed to 4500 PSI its approximate capacity is 66 cubic feet or 1869 litres. 

Sounds like you may have ordered the 4 ring Tuxing version by mistake. I got mine here.https://www.aliexpress.com/item/32952512274.html?spm=a2g0o.order_list.0.0.21ef18026Yc0Nd and the gaskets here. https://www.aliexpress.com/item/32980765403.html?spm=a2g0o.order_list.0.0.21ef18026Yc0Nd It's...

The valve has an M18x1.5 thread and a replacement can be bought cheaply on Ali Express or eBay. The foster thread will be an M10x1 but it may be difficult to find one with the twin O-ring design of the one you have. It may well be possible to use an alternate method to seal a hose of the...

Those joints require squashable nylon washers. Extras should be provided with the filters and hoses. Teflon tape is not a sealant, it's a lubricant and it is supposed to be only used on tapered threads such as NPT. The threads on these Chinese filters are metric parallel and require special...

Another likely leak possibility is the hose to bleed block union. There should also be a white nylon washer between the socket and the threaded end of the hose.

1. The YH does not use tapered threads and thus doesn't use sealing tape. Are you sure that your pump is a YH? 2. If the burst disk is ruptured, it won't build pressure but this is very unlikely if the unit has never been fully pressurized. If it is a YH, the gauge threads are M10x1. Try...
