Premium quality Polypropylene large bore threaded 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.

    Hexagonal Design

    The smart hexagonal design provides a surface for easy tool engagement with the fitting making tightening and therefore installation a simple process.

    Highest Quality Materials

    Manufactured from high quality polypropylene. The material has excellent chemical, corrosion, and UV protection. In addition, the material resists moisture absorption to ensure consistent dimensions over the lifetime of the fitting.

    Reliable, High Quality Threads

    Philmac’s large bore threaded fittings are manufactured in accordance with ISO 9001 standards, ensuring quality and consistency in the thread every time. All female fittings above 2” have precision machined threads, to minimise chance of cross threading and maximise sealing capability.

    Reinforcing Ring on Female Threads

    All female threads above 2” are fitted with 316 Stainless Steel reinforcing rings to maximise the strength of the female thread, resist expansion of the thread over time, and ensure the long-term performance.

    Pressure Rating

    Fittings are suitable for almost all applications. Pressure rated to PN12 for 2-1/2” and PN10 for 3” and 4” with a 50-year lifetime when used at a temperature of 23 degrees centigrade. The end-user can have complete confidence in the long term performance of the fitting.

  • 6

    Tapered Design

    The threads incorporate a tapered design. This ensures ease of use as the thread joint can be commenced easily but importantly this does not compromise sealing ability. The end-user can be assured of making an effective joint in as easy a manner as possible.
