Relocating the chain-joint seal between inner and outer link plates cuts pin bending stress, reduces wear, and extends lubrication life.

Bellows and reinforcing bands let the irrigation boot absorb misalignment and rotation, reducing slippage, tears, and wear in span pipe joints.

Angled pumping elements and annular ridges return leakage oil under hydrodynamic pressure while elastomer lips suppress capillary seepage.

A stepped fin seal uses inert gas, vortex guidance, and mixed-gas discharge to stop process gas jet penetration in compressors.

A curved, articulating aeroseal maintains flap-cove sealing across large displacements to reduce noise and lift loss.

An asymmetrical reversible seal between turbine blades blocks hot gas, lets cooling air escape, and simplifies installation under centrifugal loads.

Nested male and female elastomer stacks create a high-expansion wellbore seal with shorter plug length and lower setting force.

An eccentric fork-tube seal keeps dust out and oil in under radial misalignment by using offset lips that maintain contact with lower friction.

Convex lug surfaces stop circumferential seal rotation while spreading contact pressure to reduce erosion, embedding, and wear.

A rotating oil-locking hole aligns or blocks the e-liquid path, preventing leakage during storage and transport while preserving on-demand supply.

A cover contact portion adds local force at the partition wall to stop thin center plate deformation and keep gasket beads compressed.

Spring-energized double-curved metal C-seals conform to pipe surfaces for reusable high-integrity sealing in hot, corrosive, high-pressure pipelines.

Mated pull-out films and compressed gaskets let one connector join multiple fluid lines aseptically while reducing connector count and handling.

Wave-spring-biased seal sections maintain contact under deflection and heat, reducing leakage and deformation in turbine seals.

A pressurized groove uses low-pressure compressed air and explosion force to tighten an O-ring seal and block flame and pressure escape.

Seal rings, cotton, and a limit cover contain condensed e-liquid in the atomizer to keep it out of the battery assembly and prevent shorts.

A single gasket and center plate seal both casing sides, cutting water pump gasket count and weight while maintaining sealing performance.

A fire-stop lip shields the air-sealing lip in turbomachine seals, preserving air and fire sealing during high-temperature fire exposure.

A rotating metal sealing plate maintains contact under closing force and atmospheric pressure to improve vacuum sealability and service life.

Opposed foam incisions let film strips fully penetrate a sealing strip, improving vapor impermeability while protecting the film during installation.

Axial projections and housing recesses form a tortuous flow path that cuts coolant backflow and preserves pump efficiency under misalignment.

Liquid injection grooves on the shaft feed magnetic fluid directly into sealing gaps, enabling faster, more uniform filling and reliable sealing.

Flexible bristles contact the bellows to absorb seal vibration, reducing cyclic loads, mechanical stress, and seal wear.

A carbon composite-to-metal seal replaces polymer seals to resist heat, pressure, and chemical attack in downhole injection valves.

An over-molded rubber gasket secures a plastic wafer to form a low-friction labyrinth seal that limits lubricant loss and contamination ingress.

Tapered annular interfaces and exclusion chambers keep contaminants out while returning lubricant to the sump in rotating equipment.

A coaxial V-ring and secondary seal keep dust, dirt, and fluids away from the spring and bushing while allowing pivot movement.

An elastomer sealing body and conductive support body combine water-jet sealing, EMI shielding, and secure removable contact in one part.

Magnetic repulsion supports a floating ring without contact, preserving shaft clearance, reducing wear, damping vibration, and simplifying seal assembly.
