HDPE Transition Fitting | Female NPT × DIPS | Series 712 | SDR 7 - 17 | 0.5" - 2"
HDPE Transition Fitting | Female NPT × DIPS | Series 712 | SDR 7–17 | 0.5"–2"
The Series 712 Transition Fitting provides a rugged and secure connection from Female NPT Thread to DIPS HDPE pipe. This listing covers the smaller DIPS sizes (0.5"–2"), ideal for municipal, industrial, and utility-grade systems. Designed for durability, the multi-level barb system ensures a leak-resistant seal—even under pressure fluctuations and thermal expansion.
Each fitting is hydraulically compressed onto high-quality polyethylene or copolymer material and cold-pressed into the coupling's tapered steel entrance. This process creates a high-tensile grip that resists pull-out and maintains seal integrity even at zero internal pressure. Available in SDR 7, SDR 9, SDR 11, and SDR 17, these fittings are engineered for long-term performance with a 50-year design life and 2:1 safety factor at 73.4°F.
