Joints With Sealing Surfaces TRIZ Cases
- Pipe Fitting With Elastic Blocking Nut and Retained Gasket
An elastic blocking nut and retaining means prevent gasket deformation during insertion, enabling fast connection without compromising seal integrity.
- Automotive Coolant Hose Adapter for Threaded High-Pressure Lines
A composite band adapter secures threaded high-pressure coolant lines to existing engine necks without permanent modification.
- Case-Hardened Ferrule Fitting for High-Pressure Tube Sealing
A fitting design uses a case-hardened ferrule and annealed body to grip conduit ends securely.
- Sanitary Line Attachment With Inelastic Sealing Ring
A sanitary line attachment uses an inelastic sealing ring with tool engagement indents for secure installation.
- Pipe Connector With Stacked Sealing Members and Locking Member
A pipe connector uses stacked sealing members and a locking member to form a secure mechanical joint.
- Compressible Coupling With Circumferential Teeth
A compressible coupling uses circumferential teeth to interlock with a tube and prevent relative rotation.
- Microbarb Tubing Connector Fluid-Tight Seal Design
Segmented barbed connector within shell compresses against mating surface to eliminate leakage in soft tubing connections.
- Aerospace Fitting With Internal Locking Pockets
Circumferential pockets in the fitting engage internal locking balls to eliminate external lockwire hazards and reduce device complexity.
- Pipe Fitting with Rotating Grooving Element
Rotating pipe fastening element grooves interior walls for leak-proof connections without cutting pipes.
- Hybrid Plastic-Metal Pipe Connection with Retaining Ring
A pipe connection combines a polysulfone body with a brass union nut secured by an intermediary retaining ring.
- Hot Pressed Aluminum Alloy Unions for High-Pressure Circuits
Hot pressing aluminum alloy bars resolves material homogeneity issues to produce crack-free unions suitable for high-pressure pneumatic systems.
