Cherne® 44" Replacement Pad Kit

The Cherne® 44" Replacement Pad Kit (part #23748) is a factory replacement sealing pad for Cherne® Air-Loc® 44" plate-style manhole vacuum testers. The pad forms the airtight seal between the test plate and the manhole rim, and replacing a worn or damaged pad restores the tester's ability to pull and hold an accurate vacuum.

Key Features

• Genuine Cherne® replacement part — sized for the 44" plate-style manhole tester for a proper factory fit.
• Restores the vacuum seal — a worn, nicked, or hardened pad is a common cause of vacuum loss and inconclusive test readings.
• Extends equipment life — refresh your existing tester instead of replacing the entire test head.
• Field-serviceable — keeps your manhole testing program running with minimal downtime.

Applications

Used by municipal crews, utility contractors, and inspection firms maintaining Cherne® plate-style manhole vacuum testers for acceptance testing of new, existing, and rehabilitated manholes per ASTM C1244.
