This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Standard (AS) covers solid, uncut polytetrafluoroethylene (PTFE) retainers (backup rings) for use in glands in accordance with AS4716. They are for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with O-rings, packings and other elastomeric seals for static and dynamic applications.Because of the construction of groove dimensions, backup rings specific to rod applications are designated "R" - Rod (Female), backup rings specific to piston applications are designated "P" - Piston (Male). Piston and rod types of virgin pigmented PTFE are also identified by color code which also distinguishes parts to this standard from those made from virgin PTFE to other standards. This revision updates the metric conversions and includes some minor editorial changes.

Book excerpt: This Aerospace Standard (AS) covers scarf-cut 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 "R" - Rod (Female), back-ups specific to piston applications are designated "P" - Piston (Male).Retainers specified herein have been designed for a temperature range of -65 °F to 275 °F (-54 °C to 135 °C) and a nominal operating pressure of 3000 psi (20.7 MPa) for code 09 material and 5000 psi (34.5 MPa) for code 10 material. Material codes are based on AMS 3678 material types.Consideration has been made to accommodate cylinder breathing on piston applications, calculated at .002 inch/inch diameter/1,000 psi (.051 mm/mm diameter/6.9 MPa) to ensure a minimum 50% lap at -65 °F (-54 °C). This has required an increase in the diameter on certain larger sizes and a slight overlap at ambient will therefore be apparent. These parts have been designed such that the overlap at 275 °F (135 °C) will not result in axial compression of the O-rings, even in the worst tolerance stack-up situation. This standard is required so that retainers (back-up) rings will be available for use with static glands per AS5857.

Book excerpt: This specification and part standard covers polytetrafluoroethylene (PTFE) resin material and the dimensional requirements for scarf-cut retainers (back-up rings) previously covered by MIL-R-8791 and MIL-R-8791/1. The retainers are intended for use in hydraulic and pneumatic system components as anti-extrusion devices in conjunction with seals and O-rings. As a result of the 5 year review, this document has been revised to update the references and the prohibition of use of these parts in glands other than MIL-G-5514 has been further clarified.

Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Standard (AS) provides standardized gland (groove) design criteria and dimensions for elastomeric seal glands for static and dynamic applications. The glands have been specifically designed for applications using SAE AS568 size O-rings, with related class 2 tolerances, at pressures exceeding 1500 psi (10.34 MPa) utilizing one or two anti-extrusion (backup) rings and applications at pressures below 1500 psi (10.34 MPa) without backup rings. The glands have been sized to provide sufficient squeeze for effective sealing while at the same time limiting squeeze to allow satisfactory operation in dynamic applications. While this specification covers the basic design criteria and recommendations for use with standard size O-rings, these glands are also suitable for use with other elastomeric, and polytetrafluoroethylene (PTFE) based seals. For static external applications i.e. where the application is overboard and sealing to atmosphere, glands should be designed in accordance with AS5857. Revision B to AS4716 is a general update using current SAE format, minor corrections and dimensional tables added in metric units. Reference to AS5857 for static external (overboard to atmosphere) glands has also been added.

The glands have been sized to provide increased squeeze as compared to AS4716 for more effective sealing at low temperatures and low seal swell conditions. These glands are not recommended for dynamic use. Primary usage is for static external sealing.The rod dimensions are the same as AS4716. The cylinder bore dimensions are the same as AS4716 except for sizes -001 thru -011 and -104 thru -113.
