[Initium]

I know i have seen companies that provides overhauled P38 EAS valve blocks. Mine does not function correct, and to rebuild it with just the o-rings, is meaningless, unless i can get new one-way valves installed at same time.

New one can be purcased at Island4x4 for about 650gbp, livable if it fixes the problem...

The decent o-ring kits come with NRV o-rings included. Just make sure you use black nitrile kit rather than the soft orange kit.

Check the NVR tips for wear, and use the least worn one for NRV-1 to help the tank retain pressure !! Mine are well worn but work perfectly with new o-rings.

A fresh set of o-rings will have that valve block functioning properly, despite how the valves look. Sealing is accomplished by the o-rings. Clean up the valves a bit if worrisome.

I've never had any issues with rebuilt blocks save for one time... I missed that one of the ORings had a nick. Cant fault anyone but myself for missing it. Worse case scenario, I have a NOS valve block that still has the little red rubber plugs and still smells of packing cosmoline.
