Our RapidPress seals up to sizes 54mm contain small ridges. These ridges create leakage before the seal is pressed which is termed as a ‘leak before press’. By having this feature it offers an added layer of security during system start-up. In the event of an unpressed or improperly pressed joint, the seal will visibly leak, providing an immediate visual cue for potential issues that require fixing.
