The Val-Pak UltraFlow trap lid clamp ring is designed for compatible trap assemblies where secure lid retention is no longer being provided by the original ring. Clamp rings are useful because they create the hold-down relationship the lid depends on for both sealing integrity and overall confidence during operation.This replacement is especially useful when the original clamp ring is corroded, cracked, stretched, or has lost the ability to tighten properly. Replacing worn retention hardware can dramatically improve the feel of a repair, because the trap lid once again seats and secures the way it should.The V38-166 is a strong service choice when an UltraFlow assembly needs a more complete refresh rather than reusing questionable original hardware.
