Good To Know

Q: How do I know if my bellow needs replacing? A: Cracks, hardening, or water pooling near the power valve assembly typically indicate the bellow has failed and should be replaced.

Q: Does this include mounting hardware? A: This listing covers the bellow only, so confirm whether your existing clamps and fasteners can be reused during installation.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
