Dixon Quick Coupling 877-963-4966 3
Quick disconnect couplings can fail without warning! Prior to the operation of quick coupling
products, be sure to inspect and replace worn out fittings and safety devices. If a leak is
detected during operation, release the pressure from the circuit before investigating the
cause of the fluid leak. Do not use your fingers or skin to check for leaks, high pressure leaks
of fluids can easily penetrate the skin and can cause serious injury or death.
1. Always wipe the coupling cavities and faces clean before connecting a coupling.
2. Connect coupling before installation to ensure that it works properly.
3. Always check the body seals before connecting a coupling.
4. Shut-off power source before connecting a coupling.
5. Always install a Safety-Check valve on a pneumatic line and/or compressor.
6. Always use a Safety-Cable on large air lines (½" lines and larger).
7. Always use a Whip Hose on hydraulic or air tools.
8. Use dust caps or plugs when couplings are not in use.
9. If the locking sleeve is inoperable, check the safety lock.
10.Wear eye protection while connecting or disconnecting a coupling.
1. Never hit coupling valves to release trapped pressure.
2. Never leave couplings in the path of moving equipment.
3. Never use couplings near a welder, flash heat, or fire / flame sources.
4. Never use API modified sealants or over apply PTFE tape.
5. Use care if you must install quick couplings onto black iron pipe.
6. Never hit a coupling sleeve with a hammer or blunt object.
7. Never overtighten a coupling connection.
8. Never rotate a quick disconnect coupling under pressure.
9. Do not overpressurize quick disconnect couplings.
10.Never use a hose with a quick disconnect coupling to lift a tool.
Standard - 29 CFR, 1926.302 (partial):
(b)(1) Pneumatic power tools shall be secured to the hose or whip by some
positive means to prevent the tool from becoming accidentally disconnected.
(b)(2) Safety Clips or retainers shall be securely installed and maintained on
pneumatic impact (percussion) tools to prevent attachments from being
accidentally expelled.
(b)(4) Compressed air shall not be used for cleaning purposes except where
reduced to 30 PSI and then only with effective chip guarding and personal
protective equipment which meets the requirements of Subpart E of this part.
The 30 PSI requirement does not apply for concrete form, mill scale and
similar cleaning purposes.
(b)(5) The manufacturer’s safe operating pressure for hoses, pipes, valves,
filters and other fittings shall not be exceeded.
(b)(6) The use of hoses for hoisting or lowering tools shall not be permitted.
(b)(7) All hoses exceeding ½" inside diameter shall have a safety device at the
source of supply or branch line to reduce pressure in case of hose failure.
Standard - 29 CFR, 1926.603 (partial):
(a)(9) Steam hose leading to a steam hammer or jet pipe shall be securely
attached to the hammer with an adequate length of at least ¼" diameter chain
or cable to prevent whipping in the event the joint at the hammer is broken. Air
hammer hoses shall be provided with the same protection as required for
steam lines.
(a)(10) Safety chains, or equivalent means, shall be provided for each hose
connection to prevent the line from thrashing around in case the coupling
becomes disconnected.
