Spiral double-bolt clamps are designed to provide superior sealing on corrugated PVC suction hoses such as G941W, G941WT, and G1741.
Note: different manufacturers may use either a clockwise or counter-clockwise spiral in their hose. Our standard corrugated hoses spiral in the counter-clockwise direction (similar to a left hand thread), and these clamps are designed for that spiral only.
For clockwise spiral clamps, specify G38WR.
