A seal including a jacket including an annular body defining a central axis and a recess extending into the annular body concentric to the central axis, where the jacket includes at least 30 wt% of a PTFE and at least 10 wt% of a filler material, and where the filler material includes a boron-containing material, a nitrogen-containing material, a titanium-containing material, a silicon-containing material, a carbon fiber, a glass fiber, or a combination thereof, where the jacket further includes a coating; and an energizing element disposed in the recess.

A seal including: an annular jacket including a heel, a first lip, and a second lip defining an annular recess; and an insert including at least 3 prongs disposed within the annular recess contacting the heel, the first lip, and the second lip.

A seal ring (26) configured to be employed with a cross shaft (16) including a center section (17) and four shaft sections (18a, 18b, 18c, 18d) extending in four directions from the center section and formed with step faces (17a) where the center section widens out from base ends of the shaft sections outward in radial directions of the shaft sections, and with bearings (21) for mounting to leading end portions of the shaft sections. The seal ring is fitted over the shaft section and interposed between the bearing and the step face. The seal ring includes a seal lip (34) configured to contact the step face around the entire circumference, and an indentation (36) the seal lip enters by deforming when mounted to the cross shaft.

An adsorption device for compressed gas, is provided with a vessel with an inlet for the supply of a compressed gas to be treated, and an outlet for treated gas and an adsorption element is affixed in the vessel. The adsorption element extends along the flow direction of the compressed gas to be treated, between the inlet and the outlet. The adsorption element has a monolithic supporting structure that is at least partially provided with a coating that contains an adsorbent.

Provided is a valve with which a seal member is not damaged when pressure accumulated near the seal member is released. This valve includes a valve box having a valve chamber, a valve seat provided in the valve chamber and having a seat surface, a stem including, at a tip end thereof, a valve element configured to abut against and move away from the seat surface due to an operation of an actuator, a seal space provided with a seal member configured to prevent a fluid from leaking, a seal opening space formed outside the seal space, and a seal pressing member configured to press and fix the seal member to a valve chamber side. The valve box is formed with a leak hole through which the seal space and the outside of the valve box communicate.

A sealing system for sealing an annulus. The annulus is defined by a cylindrical interior and a cylindrical exterior within, and axially movable relative to, the cylindrical interior. The sealing system includes an inner seal (to surround and sealingly engage the cylindrical exterior), a seal support (to surround, and axially support, the inner seal), an outer seal (to surround the seal support and sealingly engage the seal support and the cylindrical interior), a first support ring (to sit behind an outer periphery of the outer seal), and a back stop (to surround the cylindrical exterior and axially support the seal support and the first ring).

A seal (1) is provided, in particular for a rotary ball valve fitting (2). The seal (1) has an annular body (4) that is resilient, flexible and provided with a radial lip (4′) and a rigid sealing ring (5) that are made in one piece. A valve, such as a rotary ball valve may include such a seal.

A seal including: an annular jacket including a body including a first lip and a second lip defining an annular recess; a circumferential spring disposed within the annular recess adjacent to one of the first lip and the second lip; and a floating circumferential insert, where a radial biasing force on the first lip is decoupled from a radial biasing force on the second lip.
