Claw couplings are most commonly used for conveying air and water, and are not to be used for steam applications. Common industry applications include: underground and surface mining, mineral processing, compressor and air tool industries, hire companies.

• Sure-Lock® couplings are simple, reliable and provide an airtight connection.
• This style of coupling excels where speed, easy, economy and safety are paramount.
• The "Cor-o-zig" design not only grips horizontally as the clamp tightens to prevent coupling pull-out, but also grips obliquely to prevent the coupling turning in the hose.

• Rotation of the stem while under pressure can damage the hose tube from the cutting action of the corrugated edges. This may cause premature hose failure.
• Constant vibration created by air drills, pavement breakers etc. is destructive to air hose couplings, especially the quick-acting type. To provide protection, connect one end of a 1 to 3 meter length of air hose to the tool using the heat-treated "No. 3500" Steel Nipple which withstands vibration for a longer period. Connect the other end of "Whip Hose" to the air supply with the quick-acting coupling. "Whip Hose" should remain permanently connected to the tool and should be the same diameter as the supply line hose.

• Warning: Never use Couplings for steam service! None of Dixon's cataloque information is to be interpreted to mean that this type of coupling is suitable for use on steam hose.
• The use of a Minsup Safety Locking Pin is necessary to ensure that Sure-Lock® Claw Couplings will not become accidentally disconnected. This ensures that the fittings are properly connected as the pin will not go through the holes in both couplings until the couplings are locked into place.
