adaptall retaining ring

Description & Features

Designed for use with Adaptall's modular adapter system, this retaining ring secures fitting components during assembly, helping to maintain proper alignment and connection integrity in hydraulic assemblies. The 18mm sizing indicates compatibility with corresponding Adaptall adapter bodies in that thread range.

Adaptall's interchangeable adapter platform is widely used across mobile and industrial hydraulic systems, and replacement or additional retaining rings are a common maintenance and assembly requirement. This component is sourced directly from Adaptall to ensure proper fit within their adapter series.

What exactly does this retaining ring do in an Adaptall fitting setup?

Answer by: Customer Support on Nov 3, 2025, 6:01 AM

Keeps the fitting components locked in position during assembly so everything lines up right and holds together the way it's supposed to. In a modular adapter system like Adaptall's, that kind of mechanical retention matters for connection integrity, especially when you're building out hydraulic assemblies that need to stay put under working conditions.

got an Adaptall modular adapter setup and my ring went missing, is this RR-18MM the right retaining ring for the 18mm size?

Answer by: Customer Support on Jul 26, 2025, 6:08 AM

For Adaptall’s modular adapter system, the RR-18MM is the 18 mm retaining ring meant to match adapter bodies in that same 18 mm thread range, so it is the correct replacement when your assembly calls for the 18 mm ring.
