What It Does:

The 66RW Rubber Washer provides a sealing surface inside the deadman shutoff valve assembly. Proper sealing is important for reliable valve operation and control of the blasting system.

Repeated valve cycling, age, compression, and harsh abrasive blasting conditions can eventually cause the rubber washer to harden, flatten, crack, or deteriorate.

Replacing a worn washer during valve service can help restore proper sealing without replacing the complete deadman shutoff valve.

Common Signs the Rubber Washer May Need Replacement:

• Air leakage from the deadman valve
• Valve does not seal completely
• Slow or inconsistent valve operation
• Rubber washer is cracked or deteriorated
• Washer has become hard or permanently compressed
• Deadman valve is being rebuilt as preventative maintenance

Finding Parts for Older PK Lindsay & Marco KwikFire Equipment

That's why we include the original part number and diagram item number whenever possible—so you can identify exactly what you need before ordering.

Important Safety Information:

The deadman control system is a critical safety component of an abrasive blasting machine. Completely depressurize and disconnect the blasting system before servicing the valve. After repair, verify proper deadman operation and shutdown before returning the equipment to service.
