VSH Shurjoint reducing coupling for copper tubing (2 x groove)

group: C306

The Model C306 Reducing Coupling allows direct reduction on a piping run and eliminates the need for a concentric reducer and couplings. The epoxy coated ductile iron coupling housings help to eliminate galvanic local cell and stray current problems. The specially designed rubber gasket prevents the smaller pipe from telescoping into the larger pipe during vertical installation.


Applicable copper tubing:
1)ASTM B-88 Type K, Type L, and Type M Seamless copper water tube.
2)ASTM B306 Copper Drainage Tuber (DWV).
