AS568-223 HNBR 90 Shore A O-Ring Rubber O Ring Seal for Oilfield Pumps and Downhole Tools

AS568-223 HNBR 90 Shore A O-Ring for Oilfield Pumps and Downhole Tools

Royal Way manufactures the AS568-223 HNBR 90 Shore A O-ring for oilfield pump builders, service companies, equipment distributors and maintenance teams. The featured size combines a 1.609-inch inside diameter with a 0.139-inch cross-section, giving purchasing and engineering teams a clear part reference for compatible pump housings, valve assemblies, hydraulic cylinders and downhole service tools.

This oilfield O-ring pairs the AS568-223 size with HNBR / HSN compound at 90 Shore A hardness. The size, elastomer and hardness can be specified together for equipment builds, service kits and repeat-order programs, helping teams keep their sealing components aligned with the required part number and material callout.

AS568-223 size and featured configuration

HNBR 90A for oilfield sealing programs

HNBR / HSN is a widely selected elastomer for oilfield rubber components when an equipment program calls for hydrogenated nitrile and a firm 90 Shore A configuration. Royal Way supplies this AS568-223 size for equipment builders and service teams that need a clearly identified O-ring for pump and hydraulic sealing assemblies.

The AS568 dash number gives procurement teams a practical reference for parts lists and spare-part planning. Matching the size with the specified compound and hardness also helps align the replacement seal with the equipment program’s material and assembly requirements.

Applications for pumps, valves and downhole service

Royal Way AS568-223 O-rings serve compatible glands in oilfield pump assemblies, hydraulic cylinders, valve bodies and downhole service tools. They support equipment manufacturing, workshop repair and field-service spare-part programs where buyers specify the AS568-223 size, HNBR / HSN compound and 90 Shore A hardness.

• Oilfield pump housings and fluid-end service assemblies
• Hydraulic cylinders and pressure-control components
• Valve bodies, manifolds and equipment covers
• Downhole tools, service equipment and OEM spare-parts programs
