The vibrations caused in the use of air tools make a coupling connection subject to Health & Safety Regulations. See ISO 4414:1998 and EN 983:1996 for safety requirements covering the installation and use of pneumatic equipment. A Health and Safety Guide has been produced which covers the use of pneumatic equipment. The Health & Safety Executive Guide HS(G) 39 states "requirements for quick acting couplings apply to most percussive and vibrating air tools, which may be fixed or hand held. If a quick acting coupling socket is fitted at the hose end adjacent to the tool, the plug should not be screwed directly into the inlet port but should be fitted onto a short isolation hose (0.5m to 1.5m long), thus isolating the plug and socket from the tool vibration." The International Standard (ISO 6150:1998) recommends a minimum of 300mm of flexible hose to be used between a vibrating tool and a quick acting coupling. Specifications Working pressure @ 20°C: 300lbf/in² (21bar) Burst Pressure: 63bar (3:1 safety factor) Temperature Range: -10°C to 60°C Please note - an increase in temperature above 20°C will affect the working pressure quoted above.
