>B< Press Fittings, UK

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 and Red Brass and are suitable for use with copper tube to EN 1057.

To install >B< Press, a mechanical press tool with a compatible jaw with 'V' profile to fit each size of fitting is 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.

Pressing Indicator Feature

IBP 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.

>B< Press Gas

Conex >B< Press fittings for natural gas and LPG applications are identified by a yellow coloured O-Ring and dot on the fitting body.
