Specs
Compatible with all prior SILCA disc adapters, however the adapter head height prevents the valve stem from fully engaging the gasket.
Generally the 252 gasket in a CP1 will hold a minimum 120psi on any size or type of valve stem, while it will hold 70-80psi when used with older SILCA adapters.
