>B< Press Gas, 3 Point Press for Gas Applications

Conex >B< Press Gas fittings for natural gas and LPG application are identified by a yellow coloured o-ring. >B< Press Gas is a versatile press fitting system for use with hard, half-hard and soft copper tube, providing a secure, long-life, leak-proof joint. They are available in Copper and Red Brass and are suitable for use with copper tube to EN 1057. Available in sizes 15-54mm.

Our >B< Press Gas is installed, with a mechanical press tool with a compatible jaw with a >B< profile to fit each size of fitting required. When pressure is exerted through the press tool the joint is permanently made and the fitting cannot be dismounted or re-used.

The >B< Press Gas system eliminates the need for solder, adhesives or additional jointing materials. The >B< profile has the advantage of a 3 Point Press, two mechanical presses either side of the bead and one hydraulic press crimping the o-ring. This provides a more secure joint.

Designed and manufactured with a specially designed HNBR O-ring. It has a reduced section in two positions causing leaks at low pressures when not pressed (from 0.1 to 5.0 bar). When the fitting is pressed, the o-ring material compresses, filling the gaps, securing a leak-free path. Therefore there is no need to go to full test pressure to check that all fittings have been pressed.
