Replacement burst valve for the Sig Sauer MCX Virtus PCP air rifle.

The Virtus is fitted with 2 of these (important to get them the correct way round!).
If the rifle has been overfilled the first burst valve will release for safety (this is the one with 5K written on it).
If you have regulator issues it may pass pressure from the high pressure side to the low pressure side causing this one to burst (this one has 1.8K written on it).

Both can become fatigued with age and burst prematurely.

Please select the one you require from the dropdown listing.
