1606 Stainless Steel Coupling
ROBAR 1606 Couplings are used to make a non-restrained connection between pipes of the same outside diameter. This coupling is fabricated with a range of .30” (pipe OD ± .15”) and therefore is best suited for smooth pipe with a uniform outside diameter (ex. Steel, PVC, Ductile Iron and HDPE).

Gaskets: SBR (Buna S) Rubber. Other compounds available.
Fasteners: 5/8” NC T304 Stainless Steel*. Nuts coated with anti-galling compound. Torque is 70-80 ft. lbs.
