With Greene, Tweed’s ACGT™-HP/ACGTL™-HP seals extrusion gaps and high pressures are no longer a challenge. The ACGT-HP is a bidirectional design while the ACGTL-HP is designed for unidirectional applications.
Both variations are extremely versatile and developed for highly efficient sealing performance in a variety of environmental conditions. They are engineered to handle a broad range of temperature extremes and fluid media, as well as larger standard clearance gaps. These geometries have been successfully tested in landing gear as well as other critical applications.
The newly designed cap-to-elastomer interface creates a larger contact area for more uniform load distribution over the entire circumferential length of the cap thus enhancing seal performance. A critical part of the seal’s outstanding performance is the division of the sealing and anti-extrusion components. Because the functionality of the components is separated, material selection can be targeted specifically for particular application requirements (e.g., modulus, shear strength and friction), allowing for the optimal sealing solution to be achieved.
FEATURES & BENEFITS
- Avalon® materials in cap elements provide low friction and extend service life over elastomer contact seals such as O-rings
- Hydromechanically activated anti-extrusion rings provide effective extrusion-resistance protection in both high- and low-pressure environments resulting in longer seal life
- Designed for use in existing MIL-G5514/AS4716 glands;
AS4832 are also available
