I'm wanting to change out the high pressure air hose on my yong heng compressor and was wanting to know what the thread size is and if i can get a quality replacement hose and from who?
Yong heng HPA hose thread size?

You'll most likely need to order one through Aliexpress. There are many vendors. I don't have a Yong Heng but most of the Chinese compressor hoses have a 10mm x 1 thread.
Make sure the hose you order terminates in the same configuration as the origninal. Most have male threads but my compressor has a female one one end and male on the other.
Here's a link to get you started. You might triy doing an Aliexpress search for PCP fill hose.

Most have M10x1.0 threads. You can buy an adapter to whatever you want (npt, bspp, etc) if you happen to have some spare quick connect fittings lying around. But a replacement high pressure house with the fittings will run you less than $10 on AliExpress.

I just don't trust the factory hoses that they come with. I had a bubble form on one when filling my gun at around 3k psi. I can't using it now it's stretched and I don't want it exploding on me lol

Did you ever get a hose to fit? If so, can you post a link to it? I need one with the Yong Heng M10x1 threaded male fitting on one end and a standard female Foster connection on the other end. I assume this is what you needed as well.

Stay away from the Chinese hoses like the ones that come on yong heng compressors. They are plain steel and the ends rust quickly.

Are there any made of stainless steel ? Depending on the grade of stainless steel, they can be weaker than mild steel. The hose that came with my Hill hand pump has the metal part made of mild steel as well.

I haven't seen a Chinese hose with stainless fittings. You can buy stainless fittings on AliExp but they don't list the alloy and may take weeks to get.

The fittings can be made from brass, nickel plated steel, or stainless steel. A lot of the paintball stuff is not 300 bar rated. You are absolutely right about stainless. Most stainless isn't as hard as carbon steel. Some grades aren't any harder than brass. All the hoses that come from Aliexpress or eBay are plated steel and will only rust if you damage the surface. None of mine, show any sign of rust. I'm talking about the hose ends, not the quick connect couplings.

The pressure acting on a fitting depends on the joint type. A tiny bore sealing against an acetyl washer or the ones that seal at their center never see much force. The fittings that seal with an o-ring behind their threads see way more force because they have a much larger surface for the pressure to act on.

Im new to airgunning. I just purchased an airfrce texan carbine and a yong heng compressor. I have not received either one yet. Does the compressor come with everything i need to fill the gun directly or do i need to purchase some other type of fitting?
Thanks

You should be all set. The Yong Heng compressor has a 8mm female quick disconnect fitting at the end of the output hose. Your Texan will have a male quick disconnect fitting on the tank.

I am not familiar with your rifle but I just bought a Marauder and Yong Heng and they hooked up perfectly. You will have to buy oil and probably have to buy button batteries for the temp. gauge. Also follow the break in protocol and make sure the cooling fan is drawing air in and not pushing it out. The cooling fan check is mentioned in the manual.
