Pumps, plumbing& sanitary The John Guest Group has a long established reputation as a world leading manufacturer of push-fit fittings, tube and other fluid control products. A reputation built on producing consistently high quality products with an ongoing commitment to value engineering and product development The strictest control is maintained by virtue of the fact that design and manufacture is carried out in modern purpose built manufacturing centres in West London and at Maidenhead in Berkshire. Maintaining control over the whole process from initial tool design and tool making through to final assembly and testing ensuring that only products of the highest quality are produced. The company believe it is this commitment to quality that has led to it receiving prestigious awards from many of the world’s leading testing and approvals organisations. John Guest is a preferred supplier to many international companies. The Push-Fit solution for plumbing and heating systems JG Speedfit is a push-fit system suitable for the plumbing of domestic hot and cold water services and central heating applications, including pressurised and combi systems. • Mains fed and indirect cold water systems • Vented and unvented hot water systems • Vented central heating systems • Sealed central heating systems provided temperatures and pressures comply with BS7291 Parts 1, 2 and 3 Class S • Underfloor heating Extensive tests have shown that Speedfit products will withstand temperatures and pressures well in excess of normal working conditions. Special applications Boats. The flexibility of the Speedfit System ensures it can be cabled easily around the interior and hidden from view. • Truly demountable without damage to pipe or fitting • Grip and seal connection • Superseal Insert gives secondary seal • Reduced pipe insertion force • Lightweight and easy to handle on site • Installation time reduced by up to 40% • Pipe flexibility permits the cabling of pipe through less accessible areas • No risk of fire or flames from a blowtorch • Easier to work in confined places • A permanent leak-proof connection • Corrosion free • No scale build up • Lower thermal diffusivity maintains safer surface temperature • Pipe elasticity can reduce the possibility of bursting under freezing conditions • Lead free and non toxic • Less noise from water flow and expansion / contraction • Long pipe lengths reduce the number of fittings required The JG Speedfit system uses a simple push-fit action meaning that there is no flux, flames or mess. All fittings have a grip then seal construction, made up of a collet with stainless steel teeth to grip an ‘O’ ring to provide a permanent leak proof seal. The additional benefit of ‘Twist and Lock’ is that a twist of a screwcap locks the pipe in position and provides increased compression on the ‘O’ ring for even greater security. With plastic pipe available in straight lengths or coils, the flexible system will ensure a fast, simple and reliable installation. Working temperatures and pressures Speedfit fittings suitable for central heating systems can withstand temperatures up to 114°C intermittently for short periods.Speedfit fittings shown as not suitable for central heating systems are used primarily on the domestic hot and cold water system accepting temperatures of up to 65°C.
