A comprehensive range of fittings is produced to cover most domestic and small commercial central heating and hot & cold water systems up to 28mm size. A range of manifold fittings and accessories complements the design flexibility of the Equator system. The body of the basic fitting is made from cross-linked polyethylene, the same heat resistant, tough and flexible material as for the pipe. The socket ends are reinforced with a marine grade 316 stainless steel end cap enabling the fitting to withstand the effects of pressure and end loading. The bodies of BSP screwed adaptors, valves and drain taps are manufactured in DZR quality brass. Equator push-fit joints should not be used on chrome plated copper tube, stainless steel tube or plain brass spigot ended fittings not within the Equator range.
Each socket incorporates an EPDM O-ring and a stainless steel grip ring. When pipe is pushed into the socket it first passes through the grip ring and then through the O-ring. The pipe is fully home when it meets the pipe stop in the bottom of the socket. The grip ring locks tightly onto the pipe by either tugging back on the fitting or when filling the system with water. The greater the pressure, the tighter the grip ensuring maximum resistance to pull-out pressures in excess of BS7291 requirements. When making joints with either plastic or compression fittings an Equator support sleeve must always be used. Only use Equator support sleeves on Equator pipe, never use other manufacturer¹s support sleeves with the Equator system. Marley Plumbing and Drainage advise against the mixing of other proprietary push-fit products. Where necessary or where it is unavoidable, ie. in renovation work, connection to other push-fit or copper systems is possible providing the fittings or pipe is manufactured to BS7291. Particular care is needed when using spigot fittings, as the position of any grab ring groove may conflict with the o-ring position.
