Powerlock clamps are for use on PVC suction hoses with a convulater cover. These fittings come in two different configurations. Left hand and right hand spiral. To determine which style is required look at the end of the hose: if the spiral helix runs in a clockwise direction (to the right), a right clamp is required. If the helix runs counter clockwise (to the left), a counter clockwise or left hand clamp should be used. These clamps are manufactured from plated steel. the spiral steel fits between the helices and creates a seal when tightened.
