AC/OX CUTTING/WELDING/BRAZING

Hose connectors

Hose connectors have loose hose nipples for 9 mm (3/8”) and 6 mm (1/4”) welding hose. The connecting nuts on the Oxygen couplings are right-hand threaded. The Acetylene couplings are left-hand threaded and the connecting nut has an indentation in the corners of the hexagon for easy identification. This is international practice, and gives the operator extra protection by reducing the possibility of interchanging hoses.

Hose connectors are used where long lengths of hose are needed. Screw the couplings together into a gastight joint (check with soapy water). It is not necessary to use force. Gentle tightening spares the sealing surfaces and should give a perfectly gastight connection.

Always use the correct hose couplings to connect the welding

hoses – never use metal tubing.

There are also snap-couplings for quick connection of hoses and regulators, or outlet stations, or to join lengths of hose. Such snapcouplings must be specially made for use with Oxygen and Acetylene, and so designed that the interchange of Acetylene and Oxygen hose is impossible.

Ear clamps offer a better and safer solution comparred to screw type mounting hoses. In some countries the use of screw type (worm type/jubilee clips) is not allowed. Ear clamps are than the alternative product. Screw-couplings for Gas Hoses The screw-couplings are supplied in sets. Each set consists of two hose sockets with nuts for connection to gas regulator and torch. Included is also a connection stub for using the set as a hose joint. Nuts and connection stub for Acetylene are lefthand threaded and marked with a groove.

Material is high-grade brass.
