Product Code:SAE AS5861
Title:Retainer, (Back-Up Rings), Hydraulic and Pneumatic, Polytetrafluoroethylene Resin, Solid, Static Gland
Issuing Committee:A-6c2 Seals Committee
Scope:This SAE Aerospace Standard (AS) covers solid polytetrafluoroethylene (PTFE) retainers (back-up rings) for use in static glands in accordance with AS5857. They are for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with O-rings, packings and other elastomeric seals. Because of the construction of groove dimensions, back-ups specific to rod applications are designated 驴R驴 - Rod (Female), back-ups specific to piston applications are designated 驴P驴 - Piston (Male).Retainers specified herein have been designed for a temperature range of -65 to 275 掳F (-54 to 135 掳C) and a nominal operating pressure of 3000 psi (20.6 MPa) for code 09 material and 5000 psi (34.3 MPa) for code 10 material. Material codes are based on AMS 3678 material types.【英文标准名称】:SpecificationforHigh-densityPolyethylne(PE)LinePipe
