Orbot rubber washer for spray jets
The sealing washer behind a spray jet on an Orbot machine.
The usual cause of a dripping jet
When solution weeps from around a jet rather than out of it, the washer behind it has hardened or split. It is a cheap part and a five-minute job, and leaving it means solution running down the inside of the head where you cannot see what it is doing.
Identifying the right part
Fasteners and small components change between production runs, and the part on your machine may not match the current drawing. Measure what you are replacing, or photograph it against a ruler, and send that with your model and serial number. It takes a minute and it saves an order that does not fit.

Replacing It
- Release solution pressure and remove the jet.
- Take out the old washer completely and check no pieces are left in the seat.
- Fit the new washer flat and refit the jet. Firm is enough — over-tightening squashes the washer and it will weep again.
- Washers of the same age harden at the same rate. If one has failed, check the others on the head.
Frequently Asked Questions
The jet still drips with a new washer. What next?
Check the jet thread and the seat for damage, and check the jet itself is not worn. If spray is also uneven across the head, see the Orbot quick connect tee.
How many should I order?
One per jet. Count the jets on your machine before ordering.
