Installation Push-In BSP Fittings

Our Push-In BSP Fittings can be installed quickly, easily, and completely from the outside; even in areas that are not accessible from the inside. This allows connections to be made flexibly at any flat section of the water tank; without opening or dismantling the tank.

 

Simple. Fast. Flexible. Our PP tank connectors feature an external thread from ½" to 2" and an internal thread from 3/8" to 1 ½" inside the fitting.

Tip: For liquids other than water, versions with NBR seals (diesel-resistant) and FKM seals (chemical-resistant) are available
