What the Sealing Washer does
Unlike a plain washer, a sealing washer carries a bonded or captive seal so that, when tightened, it closes the gap around the fastener as well as spreading the clamping load. On the CM-WAV it is used where a screw or stud passes through a wall of the airway or housing and that penetration must stay airtight to protect suction or keep dust in.
Signs the Sealing Washer needs replacing
Replace the sealing washer if its seal is hardened, cracked, or compressed flat so it no longer closes the joint, or whenever the fastener it seals is removed for service (the seal takes a set once compressed). A small air leak or dust weep at a bolt head is a sign the sealing washer has failed and should be renewed rather than simply retorqued.
Installation and fit
Fit the new 11385 sealing washer under the fastener head with the seal facing the surface it must close against, and tighten to seat the seal without over-crushing it. Confirm the joint no longer leaks before use. Twin City Vacuum has sold and serviced CleanMax equipment since 1956, and every part is sourced directly from Tacony.
