Philmac BSP Large Bore Fittings
Philmac’s robust range of large bore threaded fittings provide precision BSP tapered threads that have been engineered to maximise sealing performance.
The versatile range is made from high performance, UV resistant polypropylene that does not absorb moisture. Installation is quick, simple and reliable every time. The material is also potable water (AS/NZ 4020) approved.
Philmac’s threaded fittings provide maximum versatility, delivering a high performance connection across a wide range of pressure ratings and chemical combinations. The hexagonal body makes them extremely simple to install. Importantly, Philmac threaded fittings are suitable for working pressures up to PN16 for sizes up to 2”, PN12 for 2-1/2” and PN10 for 3” and 4” sized fittings.
