Leak Test Couplers can be designed for: Beaded tubes Plain tubes Threaded ports Flared connections Quick-connect fittings Custom machined ports Plastic and metal connectors
Yes. Leak Test Couplers can be integrated into: Automated test benches Robotic testing systems End-of-line testing stations Leak testing machines Production assembly lines
Common seal materials include: NBR (Buna-N) EPDM FKM (Viton®) Silicone HNBR PTFE Seal selection depends on the operating fluid, temperature, and pressure conditions.
Pressure capabilities vary depending on design and application. Standard couplers can typically operate from vacuum conditions up to several hundred bar, while custom designs can accommodate significantly higher pressures.
Sealant Enterprises connectors are engineered to support leak testing, hot testing, cold testing, and functional testing applications across automotive, HVAC, aerospace, EV, and industrial manufacturing sectors.
Yes. We manufacture both low-pressure and high-pressure leak testing couplers depending on customer requirements and application conditions. (0-450 bar)
Yes. The couplers are engineered for 100% leak-proof sealing performance when used within specified pressure and application limits.
No. Most Sealant Enterprises leak testing couplers feature a single-touch quick connect mechanism that allows tool-free operation for faster testing cycles.
Yes. Our STPC Series and specialized sealing connectors are designed to provide a secure grip without damaging sensitive plastic surfaces or soft materials.
Sealant Enterprises leak testing couplers can clamp onto: Pipes and tubes Ferrules Beads Stub ends Flanges Plastic and metal components
Our leak testing couplers are used in: Pressure leak testing Vacuum testing Burst testing Production line testing R&D and laboratory testing Pneumatic and hydraulic validation systems
A leak testing coupler is a quick-connect sealing device used to temporarily seal pipes, tubes, ferrules, stubs, or components during air, gas, vacuum, or fluid leak testing operations.
