What it is
A shear-off nut and olive supplied by Johnson & Starley for use on Hispec warm air units. The nut tightens onto the pipe to compress the olive and form a sealed compression joint, with the shear-off head designed to break away once the correct tightening torque is reached. It is a small consumable fitting used during service and repair work on the appliance's pipework connections.
Signs this part needs replacing
- Visible weeping or damp staining around the compression joint
- The olive is crushed, distorted or scored and will not seal
- The nut has been overtightened and the shear-off head has already broken away
- The nut is rounded, cracked or seized on the pipe
- The joint cannot be re-made after the pipework has been disturbed
Before you order
- Confirm the appliance model number against the fitment list above
- Check whether the existing joint uses a shear-off type nut before ordering
- Inspect the pipe end and olive seat for damage that would prevent a seal
- Allow for replacing the olive whenever the joint is disturbed
