Eaton 4629X16 O-ring 0.926 Id 1.066 Od Buna-n Black

Product Description

The EATON 4629X16 is a Buna-N nitrile butadiene rubber o-ring designed for static and dynamic sealing applications in fluid and pneumatic systems. It features a round cross section measuring 0.07 inches thick, with an inside diameter of 0.926 inches and an outside diameter of 1.066 inches. The black Buna-N compound provides solid resistance to petroleum-based oils, fuels, and hydraulic fluids, making it a dependable sealing component for plumbing, HVAC, and industrial fluid handling assemblies. Licensed plumbers, HVAC technicians, and maintenance mechanics typically install this part during system repairs and preventive maintenance.

This o-ring is suited for use in sealing connections within residential and commercial systems where petroleum-based fluids or air are present. Common applications include valve seats, pipe unions, fittings, and pump housings. Its compact dimensions make it appropriate for tight-clearance sealing points in both new installations and replacement service work. The round cross section ensures consistent compression and reliable sealing when properly seated in a machined groove.

Compatibility

Designed as an OEM-style replacement o-ring for sealing applications requiring a 0.926 inches ID by 1.066 inches OD Buna-N round cross section seal in fluid or pneumatic assemblies.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and drain the system before removing or replacing any sealing component. Inspect the mating groove for wear, scoring, or debris before seating the new o-ring. Lightly lubricating the o-ring with a compatible fluid or o-ring lubricant prior to installation helps prevent tearing and ensures proper seating.
