Safe-T-Seal MTP802 Test Plug

The Safe-T-Seal MTP802 is an 8-inch test plug designed for pressure testing rigid pipe systems. It fits inside pipes with an inside diameter of up to 8 inches and seals against natural rubber material. Plumbers and maintenance crews use it to verify line integrity before putting systems into service.

50 ft head pressure rating

This plug withstands 50 ft of head pressure during testing, which is the single figure that determines whether it matches the test requirements for a given job. If the specified test pressure exceeds that value, the plug cannot be used safely and a higher-rated device is needed.

Raised square head for tool engagement

The raised square head allows a wrench or socket to tighten and remove the plug without damaging the seal. No inflation hose, gauge or additional hardware is included, so installers must supply their own tools and any required lubricant.
