4" Flange Borg Warner Transmission Couplers

4" Split, Solid, & Short Shaft Couplers for Borg Warner Transmissions by Buck Algonquin and Poly Flex

4" shaft couplers are cast from ductile iron and precision machined to SAEJ755 specifications. 

Poly Flex produces a high quality parallel clamp steel half coupling that can be split further apart than a traditional split coupling to make installing onto the shaft even easier than a split coupling. All Poly Flex half couplings are CNC machined and plated in an SA5 Cobalt Zinc for up to 6 times more corrosion resistance than traditional zinc plating. We currently have a limited selection couplings online, but will be adding more shortly and can always special order.

 

Fits Borg Warner, Hurth and Newage marine transmissions.

  • 4" flange diameter
