JOINER BUSH BSP 1" X 1/2” PHILMAC 90413100 at a glance

Philmac’s robust 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. (Note: Products marked “Ancillary” are not potable water 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.

Smart hexagonal design makes the fittings compatible with tools and ensures that Philmac BSP threaded fittings are extremely easy to install.

Philmac threaded fittings are manufactured from high quality materials that ensure strong connections for many years.

The material also has a high degree of UV resistance to ensure long term performance even in direct sunlight.

Thread the 1" BSP male end onto your poly pipe using a hose clamp or compression fitting, ensuring a secure seal. Connect the 1/2" BSP female outlet to your secondary pipe or fitting, tightening firmly by hand or with a wrench. For barb connections, slide the barbed end into poly pipe and secure with two stainless steel hose clamps (one near the barb tip, one further back). Always check that both connections are leak-free before pressurising the system. Tips: Use two stainless steel clamps on barb connections to prevent slippage under pressure — never rely on a single clamp. For easier future disconnection, consider compression fittings instead of solvent weld if your system design allows. Always use fittings rated to at least 800kPa to match your rural poly pipe's pressure rating.
