JOINER BUSH POLY 50MM X 40MM PHILMAC 90416500 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.

Insert the barbed end of the 50mm x 40mm joiner bush into the poly pipe, ensuring the pipe is pushed fully onto the barb until it seats firmly. Secure the connection using two stainless steel hose clamps—one near the barb shoulder and one further along the pipe. Tighten clamps evenly with a screwdriver or clamp tool until snug, taking care not to over-tighten and damage the poly. Allow the connection to set for 24 hours before pressurising the system. Tips: Always use genuine stainless steel clamps to prevent rust staining and corrosion in Queensland's climate. For easier insertion, slightly warm the poly pipe end in warm (not boiling) water to soften it, making the barb slide on more smoothly. Check clamp tightness seasonally, as temperature fluctuations can cause slight movement in rural systems.
