The Hollis second-stage diaphragm retainer tool is a professional-grade, white acetal (POM-C) tool designed for servicing balanced downstream regulators, including the 212, 221, and 321 series. It ensures precise engagement with the 27046 retaining ring, preventing thread stripping or damage during maintenance.
 
How It Works:
The tool aligns with the grooves of the internal diaphragm retaining ring within the second stage casing. By applying even, distributed pressure across the threads, it allows the service technician to safely unscrew or tighten the retainer ring during regular servicing, parts replacement, or deep cleaning without causing distortion to plastic or composite housings.
