Lang 1485 Internal Retaining Ring Pliers 3-1/16 to 6-1/4 in

Product Description

The LANG 1485 is a straight-tip internal retaining ring pliers designed for installing and removing internal retaining rings in the 3-1/16 to 6-1/4 inch diameter range. With an overall length of 16 inches and a tip diameter of 0.12 inches, this tool provides the reach and precision needed to seat or extract large-bore internal rings without deforming the workpiece. A spring ratchet locking mechanism holds the pliers at the set spread, freeing the technician to reposition or make adjustments without losing ring alignment. This tool is used by HVAC technicians, millwrights, plumbers, and general maintenance professionals working on large-diameter shaft assemblies, bearing housings, and similar mechanical components.

The LANG 1485 is suited for applications involving large internal retaining rings found in commercial HVAC compressor assemblies, pump housings, large-bore pipe fittings, and industrial shaft assemblies. It is a bench and field tool appropriate for any trade professional who regularly services equipment with internal snap ring retention. The 16 inch overall length gives adequate leverage when working in tight equipment bays or deep housings where shorter pliers cannot generate enough controlled spread force.

Key Features

• Handles internal retaining rings from 3-1/16 inches to 6-1/4 inches in diameter
• Spring ratchet locking mechanism holds set spread for hands-free positioning
• Straight tip angle (0 degrees) for direct axial access to ring grooves
• Tip diameter of 0.12 inches for positive engagement in standard ring tip holes
• Overall length of 16 inches provides leverage for large-diameter ring installation

Compatibility

Designed as a general-purpose internal retaining ring pliers for large-bore applications requiring ring diameters between 3-1/16 inches and 6-1/4 inches. Confirm ring tip hole size and groove clearance against tool tip diameter before use.

Installation Notes

This tool is used by licensed mechanics, HVAC technicians, and industrial maintenance professionals. Always relieve system pressure and de-energize equipment before disassembling any assembly that uses retaining rings. Spread pliers to match ring diameter before insertion into the bore, then release the ratchet lock to allow the ring to seat fully in its groove. Inspect ring tips and pliers tips for wear or deformation before each use to prevent tip disengagement under load.
