What it is
The Worcester Bosch EP70 O-ring is a replacement seal sized 7.59 mm x 2.62 mm, supplied under part number 87161057920. It belongs to the Worcester Bosch range of gaskets, O-rings, seals and washers used across the Junior RSF appliance family. Its job is to sit in a machined groove and compress between two mating faces, closing the joint so water cannot track past it.
O-rings of this size are consumable items. Heat, pressure cycling and limescale gradually harden the rubber, so the seal is normally renewed whenever the joint it serves is opened.
Signs this part needs replacing
- Weeping or a visible drip at the joint the O-ring seals
- Water tracking down pipework or staining around the connection
- The ring feels hard, brittle or flattened instead of pliable
- Cracks, nicks or a squared-off cross-section visible once the joint is opened
- Scale or corrosion debris sitting in the seal groove
Before you order
- Check the GC number on the appliance data badge against the compatibility table above.
- Confirm the existing seal size and part number, as more than one O-ring is used across the Junior RSF range.
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
