Grooved Metal Hose

This flexible connection combines grooved quick-installation with stainless steel corrugated steel and braided mesh sleeves. It requires no welding, offers fast installation, and is temperature and pressure resistant. Ideal for fire protection, HVAC, water supply and drainage, and pump rooms.

PTFE Flanged Metal Hose

PTFE flanged metal hoses are composite flexible pipe fittings with an inner layer of polytetrafluoroethylene (PTFE) and an outer layer of stainless steel corrugated/braided mesh.

Rectangular Non-Metallic Compensator

Designed specifically for rectangular air ducts, flues, and ventilation pipes, it uses non-metallic flexible fabric as its main body. Relying on fabric deformation to absorb displacement, reduce vibration, and seal, it is a commonly used compensation component in high-temperature, large-diameter ventilation and smoke exhaust systems.

Clamp-type Duckbill Check Valve

Mainly used in sewage systems, discharge systems, water pump outlets, booster pump stations and submersible aeration systems.

Flanged Duckbill Check Valve

Flanged duckbill check valves are flange-connected, all-rubber flexible check valves that automatically open and close based on pressure difference. They provide forward drainage and zero leakage in reverse flow to prevent backflow.

Dual-Flange Built-In Duckbill Valve

Embedded duckbill valve, in-pipe rubber check valve. Unlike external clamp duckbill valves, the rubber duckbill core is entirely installed inside a steel flange cylinder, connected in series in the middle of the pipeline.
