Materials
Nitrile (NBR) - Acrylonitrile in medium to high content levels, assuring maximum physical properties and fluid compatibility.

Hydrogenated Nitrile (HNBR) - James Walker compounds the material, yielding both physical and chemical properties well above other commercial grade products.

Fluorocarbon (Viton ®) - While others may use fillers and processing aids to artificially lower initial costs, the James Walker “No Compromise” policy guarantees compounded products of the highest quality.

NBR, HNBR, and Viton ® are available as homogeneous or fabric reinforced products.

Other special materials include: Elastolion HNBR, EPDM, Silicone, Viton GF, GLT, Neoprene, Kalrez, Acrylic, Butyl and Natural Rubber.

Continuity Molding
Regardless of diameter requirements, with our continuity press molding technique for solid seal rings, there is no theoretical size limit. James Walker Manufacturing has produced solid seal rings up to fourteen feet in diameter!

Temporary Tooling
Small quantities of large diameter seals often result in tooling that is cost prohibitive. James Walker's temporary mold facility is the solution. With comprehensive, on-site casting and machining facilities, we manufactur molds in a recyclable alloy at a fraction of the cost of conventional tooling methods.

Our Temporary Mold resource is ideal for small runs, prototypes, experimental seals and other situations where machinery repair or modification may have created a non-standard size product requirement.

Oilfield Seals
James Walker produces a full range of standard and custom seals for "downhole" and surface services.

· Spring seals and 'T' seals - internal and external

· Marine swivel and tensioner seals

· Downhole packers, hangerseals

· Standard and custom 'O' rings for explosive decompression (ED) applications such as ball valves and compressors
