Access guide
Use the offset body when clearance is the problem.
Offset ratchet wrenches help keep hands clear of surrounding panels, pipework and equipment edges. The straight reversible wrench is a fast choice when the access point is open and the fitting size is already covered.
Service workflow
Check the fitting before applying torque.
Select the square or hex opening that fully seats on the valve or fitting.
Set the reversing mechanism before tightening or loosening the fitting.
Keep the wrench square to the fitting to avoid rounding or slipping.
Use controlled pressure and avoid over-tightening service valves or caps.
Tool care
Keep the ratchet clean and ready for service work.
Wipe the wrench after use, keep the ratchet mechanism free of debris and check the reversing action before starting the next job.
Use notes
- Use the correct opening size for the valve or fitting.
- Do not force a wrench that is not fully seated.
- Keep fingers clear of pinch points and surrounding equipment edges.
- Follow site procedures when working around pressurised systems, fuel gases or refrigerant equipment.
