Safety Grooved Hose Coupling Clamp

Main Description

• • Common Grooved Layflat Fire Hose Coupling Clamps offer a flexible mouting work for different connection. The two parts of the aluminum split flange are fixed together with bolts, and the grooves on the flange match the corrugations of the hose, allowing for quick on-site installation. During fluid transportation, it avoids direct contact between metal and the medium, thus ensuring smooth flow.

  • Designed to be used in conjunction with EN14420/DIN2817 smooth tail fittings. Split clamps are designed to fit snugly on the hose cover.Best practice is to use a longer 'slave' bolt initially to pull down the clamp, then use the socket bolts supplied to tighten the clamp so that there is a uniform small gap visible between the top and bottom clamp. The design ensures a mechanical lock between the clamp and the specially designed safety retaining collar on the DIN 2817 coupling. The internal ribs of the clamp are designed to 'bite' into the hose cover when tightened without damaging it, but offer a very secure and proven safe method of attachment.
