Couplings & Reducing Couplings

Philmac fittings are industry-standardized and provide the most reliable fit for your water systems to ensure optimal water flow and durability. 

  • There are 2 types of HDPE pipe: Inside control diameter (ASTM D2239) and Outside control diameter (ASTM D-3035)
  • We only support outside control diameter HDPS pipe
  • Philmac fittings we carry are made for the outside control diameter pipe
  • 3G compression fittings are pressure rated to 230psi to meet the needs of the high control diameter pipe and high-pressure systems
  • Built to withstand the toughest conditions to ensure longevity and durability, 3G compression fittings have a 50-year+ design life
  • High Performance: Made from advanced thermoplastic materials: 3G ID series compression fittings are manufactured from lightweight, high-performance thermoplastic materials which, unlike metal fittings, resist corrosion. Therefore, significantly minimizing maintenance, repairs and long-term costs
  • Materials are non-toxic and taint-free and offer outstanding impact, UV and chemical resistance
  • Special order the CTS-OD and the IPS-ID fittings but you must call in

  • No returns on these products when special ordered
