We have been manufacturing and selling pipe fittings for more than 20 years, selling low prices and producing high quality pipe fittings are our obvious advantages, welcome to inquire.
Quik-coup single-bolt rigid groove coupling is an efficient pipe connector designed for rigid applications. Its simple single-bolt fastening mechanism makes installation easy and quick, and does not require welding, reducing labor costs while ensuring high pressure resistance and durability. It is very suitable for fire protection, HVAC and industrial piping systems.

Advantages
- Single-bolt locking structure: Traditional flanges require many bolts, but the single-bolt locking structure only requires a single high-strength bolt for quick tightening, reducing installation time.
- Rigid connection: There are no moving parts, the structure is very stable, suitable for fixed pipeline systems, and can withstand high pressure (typical working pressure: 16~25 bar).
- Triple sealing:
C-type EPDM rubber ring: temperature resistant range (-40°C~120°C), chemical resistant.
Clamp compression: Enhanced sealing by mechanical occlusion of grooves and clamps.
Pressure adaptive: When the internal fluid pressure increases, the sealing ring expands to enhance the sealing effect.
