Hydraquip’s WRAS Approved Hose Assemblies

Some non-metallic materials (including natural and synthetic rubbers and a few plastics) are unsuitable for use with wholesome water, because they support extensive microbial growth, impart a very strong, unpleasant taste and odour or release toxic substances to the drinking water. – Extract courtesy of WRAS

WRAS Approved Hoses

As the UK’s largest manufacturer of bespoke braided hose assemblies, Hydraquip recognise the imWRAS Approved Hoses Assembliesportance of supplying the correct type of hose for a variety of industries. As demand and awareness has increased, Hydraquip have broadened their product base and manufacture a variety of WRAS Approved Hoses in three types of tube each with their own target market.

Hydraquip’s most popular range of WRAS approved hoses are their stainless steel overbraided, WRAS approved EPDM rubber hose, which has a smoother bore than standard EPDM rubber to lessen the build up of bacteria and the ability to be used in applications where potable water is present. These WRAS hose assemblies, which also meet the BSRIA specifications, are available in bore sizes up to 1″. A large choice of end fittings such as traditional threaded males, females, female elbows and pushfits are available as well as being part of Hydraquip’s made to measure service where hoses can be made to order to suit most requirements. Prior to WRAS introducing their guidelines for WRAS approved hose assemblies, Hydraquip saw the need to differentiate these hoses from standard EPDM assemblies and so began to add a red fleck in the braiding and markings on the WRAS stainless steel ferrules that are used. By doing this, Hydraquip’s hose assemblies already incorporated many of the requirements later needed for a WRAS approved hoses and now fully comply with these regulations.

For catering applications, Hydraquip offer the market leading Aquavend hose range which is available in bore sizes up to 1″ and is part of their made to measure service. With a wipe clean finish and no dust build up, the WRAS approved polyester elastomer tube, textile braid and white PVC cover of these hose assemblies are suited to most catering applications such as vending, water coolers, ice machines and water softeners, and are available with a choice of plastic and brass end fittings. This type of hose can also be used in hospital and Health Service environments.

In the UK Health Service where rubber is not accepted, an alternative to EPDM hoses are Hydraquip’s WRAS approved PEX (Cross Linked Polythene) lined stainless steel overbraided hoses. The UK Health Service issued the Estates & Facilities Alert DH (2010) 03, highlighting the potential weaknesses of EPDM hoses in certain applications. To offer an alternative Hydraquip can manufacture hose assemblies with a stainless steel overbraided PEX (Cross Linked Polythene) tube, which are again available on a made to measure service with a choice of plastic or brass end fittings including threaded, compression and monobloc. The properties of PEX make it an option when considering hoses for hospitals and health centres giving managers the confidence and knowledge that these hoses meet the required standard. Another benefit of Hydraquip’s PEX range is the flexibility when compared to other similar types of hose which are often marketed as PEX but are a cheaper alternative.

All of Hydraquip’s hoses and WRAS approved hoses are available on short lead times, with some stock items being shipped on the day of purchase. As well as WRAS approved hoses for drinking water, Hydraquip’s Braided Hose Division can also offer a wide variety of hoses for heating, plumbing, oils, gases and steam, to name a few, including nitrile and stainless steel convoluted hose assemblies.
