Standard Machine Grooved Transition Fitting | IPS | HDPE to Steel | SDR 7–17 | 125–335 PSI
Integrity Fusion Standard Machine Grooved Transition Fittings provide a robust, corrosion-resistant connection between HDPE and grooved-end steel piping systems. Each fitting is precision-machined with an internally beveled groove for a secure mechanical joint that operates at the maximum allowable operating pressure (MAOP) of the connected pipe SDR. Built with epoxy-coated carbon steel collars, these transitions ensure full HDPE coverage through the collar for a piggable, corrosion-free bore that protects against electrochemical and environmental wear.
Designed for use in municipal, industrial, geothermal, mining, and process piping applications, these fittings are compliant with ASTM D3261, F1598, F1599, AWWA C901/C906, and NSF/ANSI 61 & 372 standards, providing long-term reliability and strength in both pressure and non-pressure systems.
Key Features & Benefits
- Precision Grooved Steel Collar — Internally machined and beveled design ensures a secure mechanical joint and easy coupling alignment.
