Hydraulic and Automation Warehouse (HAW) now supplies lightweight 700 bar hoses with high abrasion-resistant covers, mainly used on hydraulic tooling. A significant step up from the standard hydraulic hose imported by HAW, the company now manufactures hose assemblies with this niche hose, which has a 4:1 safety factor and burst pressure rating of 2 800 bar.
The hose core is constructed from thermoplastic elastomer and has a polyurethane covering, consisting of one or more braids of aramid fibre and one braid of steel wire. The hose can be used in environments ranging from -40° to 100° C (although 70° C should not be exceeded when transferring air and water based fluids).
The hose is ideal for very high-pressure lines in compact hydraulic systems operating at 300 to 700 bar. Commonly used with rescue and safety equipment, the low change in length means that the hose can be used to transfer petroleum, synthetic or water-based fluids in hydraulic systems.
Manufactured in 6.4 and 9.5 mm diameters, the hose is available in a range of colours, including black, red and light blue covers.
HAW also boasts its own test facilities, meaning that all hose assemblies can be subjected to static hold pressure tests upon request.
The high stockholding of this hose range is accompanied by hose fittings and protective springs. All fittings stocked are 1/4" and 3/8” NPT male and HAW also stocks 700 bar quick release couplings that work hand-in-hand with the hose assemblies.
