PCP air compressor sealing ring kit, cylinder O-rings & check valve and rupture discs & washers, a complete set of daily maintenance parts dedicated to spritech series compressors

I believe I reviewed this before installing the kit and now that I've rebuilt my spritech pcp pump I'm back to confirm this is a great kit, comes with much more than pictured. only thing it lacked in my case was one of the brass check valve pieces, it did have another one in there but not the same as in my pump. but non the less a very good kit

The kit contained more parts than pictured. Included both sets of piston rings (2 on each piston) and several o-rings which I wasn't sure where they went. As others have said- No instructions are included, but I found a few videos out of China which showed the entire procedure. Best one is w/o sound and its 30 + minutes. Having a heat gun helps get the piston rings off and on. The piston rings are two pieces - one rubber o-ring and a nylon outer ring. Make sure to clean up the parts and lube the cylinder and pistons, a little heat helps in reassembly. Compressor work well now, got nearly 2 years out of the original. There is a little break in period after rebuilding. Try this before buying a new one- saved me 200+ bucks over a new compressor.

The kit is exactly what I need. The plus side is that the kit works once figured out how to install them. The down side is that this kit should've come with an instruction, especially with the piston ring installation.When installing the plastic piston ring, be careful not to jam it, it will break. I tried to force the piston house on it and I sheared it in a diagonal cut. To help the plastic ring into the housing, use a dull flat tool to help push it into the slot while apply small force to push into the housing. Even the ring was sheared in half, I was able to put it in the piston and still functional. I ordered two more kit for spare, because the seal rings can only last about 8-10 filling. They will need to be replaced every so often. Someone need to come up with a more durable rings.

it replaces all the O-rings and seals on the Spritech VE3, just make sure you have a heat gun for the PFTE- Bronze seals, makes them a little more flexible, the large green o-ring is in the kit, the small green has been replaced with a brown O-ring, I'm pretty positive these are Viton O-rings, higher heat range, make sure you lube the cylinder with Silicone oil or Synthetic oil.

Muy bueno

It contains all the necessary items to repair the worn seals of the compressor. The addition of some silicone oil would have been nice. I was able to restore my burnt out compressor to its previous working condition. I will most likely have to order this kit again and will not hesitate to do so.

Looks good will know better when I rebuild my compressor
