I have 2 Tuxing 4500 psi compressors, one of them I Ordered on July 14, 2021 and the other Ordered on April 5, 2024, and for longevity of these or any compressor is to keep it cool and not just the head temp but also the oil to help ward off thermal break down, also to use the right oil for the type of compressor you using and the Tuxing twin cylinder is a reciprocating .
TRIAX Kompressor MV 100 / SAE 30 - Full Synthetic, Multi-Vis Air Compressor Oil - Commercial Grade - For Rotary, Vane, Screw, and Reciprocal - High Temp, 20,000 Hour Life, Non-Detergent (1 Gallon)
Here are some reasons why you should not go over the 4500 psi!
absolutely should not exceed 4500 PSI when working with compressors designed for that limit. Here's why:
- Safety Risks: Compressors are engineered with specific pressure limits, and exceeding them can lead to catastrophic failures such as bursting hoses, damaged tanks, or even explosions. The Tuxing twin-cylinder and similar models are specifically rated for 4500 PSI, and pushing beyond this limit compromises their structural integrity.
- Component Wear and Tear: Operating beyond the recommended pressure accelerates the degradation of seals, valves, and other components, which can lead to costly repairs or complete compressor failure.
- Void of Warranty: If someone exceeds the pressure limit and damages the compressor, it voids the manufacturer's warranty. This means you're on your own for any repairs or replacements.
- Regulatory and Legal Concerns: Depending on your jurisdiction, exceeding specified limits on high-pressure equipment might be against safety regulations. This could expose you to liability issues in case of accidents. It would be wise not to go over the 4500 psi.

Why do you have 2? ..is the second one because of the few design changes they added? Like the closed loop cooling system and the pre air drier and the coiled air line from compressor head to filter tower (I like that one the best)
I use synthetic Amsoil in mine. It's been working fine. Maybe an oil cooler might not be a bad modification down the road.
I upgraded the water pump and have one for each head. They pump more GPM but more importantly, they have higher head pressure rating, so I can pump the water to a higher elevation after it leaves the head. This way, it can be pumped into a camping shower head and rain back down into the open holding tank. This cools the water down significantly. I haven't done any testing, but it seems to work as good as when I had it trickling down a cooling tower I made from the guts of a wall radiator (for heating).
I took your list of concerns into consideration before I decided to up my pressure on my PRV. I'm pretty sure I covered them all in my various replies to the same concerns posted by others. The only time HPA is an explosive hazard that would cause bodily injury is when a high enough volume of it is able to be released through the right passage, one that the compressed air would cause to instantly expand in a way to be considered explosive. That would be in a tank. These compressors don't have tanks. I'm not advocating to anyone that they should overfill any tanks, bottles or cylinders.
I got mine in 2021 or maybe 22. It's served me well and has way outlasted my Yong Heng compressor. When I got it, I thought it would be the last compressor I would ever need, pressure and volume wise, although I knew it wasn't going to last forever.
Being that it's rated for 4500 PSI, I know it's passed a pressure test of no less than 6750 (1½ x 4500) PSI. I also noticed how much the prices of these compressors has drastically been reduced. A stripped down compressor can be had for under $250. Any part that's going to wear out due to the added 500 PSI will be included. The tank I'll be filling to 5000 PSI is designed to handle that much pressure and has been tested to at least 7500 PSI. There's no way they'd be allowed to sell these things if they are on the verge of failure right out of the box, nor would they be so popular if they did.
As for any warranty goes, mine's been out of warranty for a long time, but even if it was still under warranty, good luck to anybody trying to cash in on it. I think the closest thing you get to a real warranty on this thing is if you bought it from Amazon. You get that one month to return it. Unless you get it between October and December then you'll get to the end of January if you say it was a Christmas gift.
So all things considered, for me, the reward outweighs any risk. As of today, I can burn up four of these compressors before I'm at the price of a 7,000 psi compressor and who knows how long they're going to last.
