Philmac threaded bushes are used to decrease or increase the thread size on existing fittings or pipes. Philmac Bushes are manufactured from high performance, UV resistant polypropylene material that prevents moisture absorption and sustains product dimensions. The chemical and corrosion resistance provides reliable, long life connections suitable for diverse applications and is a cost effective alternative to metal fittings. The precision BSP tapered threads maximise sealing performance and the hexagonal body makes them easy to install.
