New Yelomine® 2", 3" & 4" Molded Couplings
Beginning in February 2019 NAPCO will begin transferring production of 2", 3" & 4" couplings from fabricated to molded production.
The transition to molded fittings will be made on a rolling basis by size and type (e.g., permanent & non-permanent). As fabricated fitting inventory is depleted molded fittings will be shipped. To simplify ordering, current part numbers will be retained (i.e., part number will not change). Molded parts’ list pricing will also remain the same as their fabricated counterparts’.
Molded couplings offer the following advantages:
- One body style for both permanent and non-permanent versions. O-rings will be either permanent or non-permanent depending upon the version ordered
- The molded vs. machined spline groove will make spline insertion even easier
- Incremental improvement and consistency in dimensional accuracy (e.g., weight, wall thickness)
Note that like fabricated fittings, the molded versions are sized to ASTM D2241 and meet ASTM D3139 requirements. Yelomine IPS pipe meets ASTM D2241 requirements.
