Reinforced Silicone Caps are compatible for use with coolant, water, air, turbocharger bypass valve ports, vacuum ports, throttle body water ports, heater cores, and much more. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

Our highly flexible silicone hoses are manufactured to the highest standard and are perfect for many applications including radiator pipes and air/intake pipes within modern engines. To make the joint, the tube and fitting are assembled, and the compression nut tightened with a spanner. Designed to fit over metal / hard pipe outlets you wish to block off or protect from dust or debris. CNC machined and polished finish, designed to push inside a hose and provide a strong secure seal in any silicone hose, without slipping out. Manufactured from duplex brass, dezincification resistant alloy (DZR) or gunmetal, the Kuterlite range offers choice and versatility.

Compression fittings are ideal for working in confined spaces where copper pipe would be difficult to solder. This quick and simple action compresses the compression ring onto the tube, creating a sound mechanical joint. Lead times are shown on the product and trolley pages and are always advertised in working days (Monday to Friday).

Push-fit Polyplumb fittings feature a one step jointing process and a high performance stainless steel grab ring within the fitting, ensuring superb joint integrity.

Brass plumbing fittings are best suited for hot water distribution as they can withstand high temperature. Use Polyplumb with Polypipe grey polybutylene pipe, or you can combine Polyplumb fittings and copper pipe. The joint is formed by tightening a nut and compressing the olive (included with fitting) onto a copper or plastic pipe, which forms the seal.Reinforced Silicone Caps are manufactured just like reinforced silicone radiator hoses with 3 layers of polyester webbing for reinforcement. One of the major advantages of compression fittings is that the installer joins the tube by mechanical means. This heat-free system means no hot works permits are required, and joints can be made where it would otherwise be dangerous to use a naked flame.
