>B< Press Plumbing Fitting - The Secure Crimp Joint
Conex >B< Press fittings are user friendly and very quick to install, leading to savings on labour costs. It also offers the advantage of a flame free installation, therefore posing no fire risk. Conex >B< Press 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 (from stock) and Red Brass (on request) and are suitable for use with copper tube to EN 1057. Our >B< Press 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 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.
Conex has developed a unique pressing indicator, a specially designed EPDM 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. This >B< Press feature is available in fittings sized 12-54mm and suitable for hot and cold water applications.
