Ideal Washer 38.5 x 29.5mm Fibre 177278

The Ideal 177278 is a fibre washer measuring 38.5mm x 29.5mm x 2.0mm, supplied as a spare part for Ideal Commercial appliances. It fits between two mating faces in a water-carrying joint and compresses under load to form a watertight seal. Fibre is used where a firm, non-metallic seal is needed at a flat face, and washers of this type are a routine service item on commercial plant where joints are opened during maintenance.

• Weeping or dripping at the joint the washer seals
• Water tracking along pipework or staining around the fitting
• The washer has flattened, hardened or gone brittle with heat and age
• Visible cracking, swelling or deformation of the fibre
• A drip that returns shortly after the joint is re-tightened

• Confirm the appliance model and, where shown, the GC number against the compatibility list.
• Measure the existing washer against the 38.5mm x 29.5mm x 2.0mm dimensions before fitting.
• Note the alternative number 1782965 when cross-referencing older documentation.
• Isolate the water supply and depressurise the appliance before opening any joint.
