This Site Is a Condensed Guide to Engineering and Design Considerations for Metal Seals
Parker Hannifin specializes in high performance engineered seals and sealing systems. In addition to its diversified line of sealing components, Parker offers fully engineered sealing systems for specialty applications over a wide range of challenging environments. Our highly respected jet engine seals are widely used in commercial and aerospace engines and include metal E-rings, metal C-rings, metal O-rings and AS1895 seals. Parker also supplies cryogenic and high temperature metallic seals to various major rocket programs, previously including the Space Shuttle's Main Engines (SSME).
Metal seal products are engineered and manufactured at Parker's Advanced Products Business Unit (APBU), part of Parker CSS Division, in North Haven, Connecticut. Parker Hannifin holds ISO 9001, AS9100, FAA approvals and various NADCAP approvals for special processes.
We offer a variety of sizes, shapes, cross sections and materials to satisfy the sealing needs of your extreme environments. Below you will find an overview about our capabilities along with information on size and material selection, technical information and additional seal styles that we offer.
GENERAL METAL SEAL INFORMATION
How To Use the Metal Seal Design Guide
Resilient metal seals are offered in a variety of sizes, shapes, cross sections and materials to satisfy the sealing needs of your extreme environments. The metal seal part number defines all of the key design elements. This design guide provides a rapid, unambiguous, self-selection process with all the features, applications and limitations of each product clearly stated. We've organized this site into sections to easily allow you to determine the part number of the metal seal that is right for your application.

WHY CHOOSE PARKER METAL SEALS?
The most extreme environments demand metal seal sealing solutions. Resilient metal seals meet the challenges of high temperatures or cryogenics, high pressures or hard vacuum, corrosive chemicals and even intense levels of radiation performing dependably year after year.

INDEPENDENT OPTIMIZATION OF FUNCTIONAL COMPONENTS
Each discrete function including load, springback and outer sealing layer ductility/hardness can be optimized to ensure highest seal performance in every situation.

DIRECTLY BONDED ELECTROPLATING
Direct bonding onto the load bearing substrate eliminates unnecessary parts and failure modes.

PRESSURE ENERGIZATION
Internal hydrostatic pressures supplement the self-energization forces from the tubing, jacket or spring. This helps at high pressures over 3,000 psi (21 MPa) enabling sealing at 25,000 psi (170 MPa) and beyond, without risk of blow-by during proof or burst testing.
TOTAL METAL SEAL SERVICE
Service covers custom and standard sized seals from 0.250" to 150" (6 mm to 3.8 m) in diameter, including circular and non-circular shapes. We also offer the complete range of MS metal O-ring sizes, all AS1895 E-ring sizes, and the fastest delivery of C-rings from our preferred size list.
RAPID RESPONSE AND JIT (JUST-IN-TIME)
JIT deliveries are assured due to design, testing and most manufacturing processes (including roll and die-forming, machining, welding, heat-treatment, electroplating) being performed within our own facilities.
PREFERRED SOLUTION
With stringent pollution and leakage legislation, plus the demand for greater efficiency and lifetime reliability, metal seals provide the highest integrity sealing solutions for jet engine and space applications as well as oil, gas, chemical equipment, plastic molding, and diesel engine markets.
