Tavlit – Self Seal Plug PP 3/4″ Male Thread 10 bar

Rated to 10 bar working pressure, this 3/4″ male-thread polypropylene plug from Tavlit’s Self Seal range delivers a tool-free, leak-free seal wherever an open female port needs to be closed off — on pool pipework, filter manifolds, chemical dosing lines, or irrigation headers. The pre-assembled EPDM O-ring eliminates the need for PTFE tape and ensures a consistent, repeatable seal every time.

Self Seal system & sealing

Tavlit’s Self Seal concept centres on a factory-fitted EPDM O-ring that seats against the female socket face as the plug is hand-tightened. Because the seal is compressive rather than thread-dependent, there is no risk of overtightening or cross-threading, and the plug can be removed and re-fitted multiple times without losing sealing integrity. EPDM is resistant to chlorine, pool chemicals, and common fertilisers, making this plug equally at home in pool plant rooms and irrigation systems.

Material & pressure rating

Moulded from polypropylene (PP), the plug resists corrosion, UV degradation, and the chemical environment of pool plant rooms far better than brass or steel alternatives. The 10 bar pressure rating comfortably exceeds the working pressures seen in domestic and commercial pool circuits, providing a generous safety margin for systems subject to water-hammer or pump start-up surges.

Compatibility & application

The 3/4″ BSP male thread is the most common port size on pool filter multiport valves, chemical dosing tees, and manifold blocks, so this plug serves as a practical spare for any pool installer or service technician. It also pairs directly with the wider Tavlit Self Seal fitting range — elbows, tees, nipple sockets, and couplers — making it straightforward to extend or cap off a compatible pipework system without switching fitting families.
