Ridgid 34422 O-ring 4.5x4.625x0.0625 in Buna-n

Product Description

The RIDGID 34422 is a replacement O-ring manufactured from Buna-N (nitrile) rubber, sized at 4-1/2 inches inner dimension by 4-5/8 inches outer dimension by 1/16 inch cross-section. Buna-N compound offers solid resistance to petroleum-based fluids, oils, and moderate hydraulic media, making this O-ring a practical sealing solution for power tool and pipe tool assemblies. Plumbers and pipe-fitting professionals who service RIDGID power drive and threading equipment rely on correct-dimension O-rings to maintain fluid-tight seals and prevent equipment downtime. This part is an OEM RIDGID accessory, ensuring dimensional accuracy for a proper seat and reliable service life.

This O-ring is intended as a direct replacement component for compatible RIDGID power tools and pipe-threading accessories. It fits into sealing grooves where the 4-1/2 inch by 4-5/8 inch by 1/16 inch dimension spec is required. Typical applications include pipe threader oil reservoirs, pump housings, and similar assemblies that use O-ring face or groove seals to contain threading oil or hydraulic fluid during operation.

Compatibility

Designed as an OEM-style replacement O-ring for RIDGID power tools and pipe-threading accessories requiring a 4-1/2 inches x 4-5/8 inches x 1/16 inch Buna-N seal. Consult the RIDGID parts breakdown for your specific tool model to confirm fitment before installation.

Installation Notes

O-ring replacement on power tool and pipe-threading equipment is typically performed by a qualified service technician or licensed plumber. Power down and unplug all equipment before disassembly, and drain any residual threading oil from the reservoir or housing. Inspect the sealing groove for nicks or debris before seating the new O-ring, and apply a light coat of compatible lubricant to the O-ring to ease installation and prevent pinching. Do not overstretch the O-ring during installation.
