High-Quality OEM Grooved Coupling Factories Pricelist – Reducing Flexible coupling 300Psi – DIKAI

Style 1NR Reducing Flexible Coupling

1.Product Introduction
The reducing coupling allows for direct reduction on a piping run and eliminates the need for a concentric reducer and additional couplings. The specially designed rubber gasket helps prevent small pipe from telescoping into larger pipe during vertical assembly.

Caution: The Model 7706 couplings must not be used with an end cap, as the end cap could be sucked into the pipe by the vacuum created when a system is being drained.

•Style 1NR is a reducing flexible coupling.Two ends can connect to different diameter of steel plate to avoid telescope by vertical installation.
•The structure ensures lower cost and faster installation under the premise of ensuring the strength.
•Enhanced body resists 4 times working pressure.
