Red PRV 1881 Cap Combo (35psi / 2.5 bar)

A PCO1881 cap fitted with a red pressure relief valve set to 35psi (2.5 bar). It’s designed for KegLand’s PCO38 tapping head for the PET mini keg range. Because it uses the standard PET bottle thread (PCO1881), it also fits the FermZilla collection container and lid.

Specifications

• Thread: PCO1881 (standard PET bottle thread)
• Pressure relief: 35psi / 2.5 bar (red PRV)
• Suits: PCO38 tapping head, FermZilla collection container and lid

Please note

Never exceed the pressure rating of your vessel. A pressure relief valve is a safety device, not a spunding valve, so don’t use it to control fermentation pressure. Use an adjustable spunding valve such as the BlowTie for that.
