What it is

The pump inlet O-ring is a Johnson & Starley sealing component for the pump-to-hose connection on Reno boilers. It provides a hydraulic seal at the pump inlet, helping prevent water loss from the heating circuit. This O-ring is listed for use across a range of Reno models.

Signs this part needs replacing

  • Water weeping or dripping at the pump-to-hose joint.
  • Visible cracking, flattening or hardening of the O-ring.
  • Recurring pressure loss or air ingress in the heating circuit.
  • Damp staining or scale around the pump inlet connection.
  • The O-ring has been disturbed during pump or hose work and no longer seals.

Before you order

  • Check the boiler model against the fitment list above.
  • Confirm the part is for the pump-to-hose connection.
  • Inspect the pump inlet and hose sealing faces for damage or debris.
  • Isolate the appliance and depressurise the system before fitting.
