Made in Japan
Manufacturer: Naigai Rubber Industry Co.,Ltd
Model: R/RM Type

Features

• Anti-vibration effect

EP JOINT, which has a small spring constant, is effective in preventing vibration.

• Displacement absorption

EP JOINT, which has excellent elasticity and shape recovery properties, protects piping by absorbing displacements such as eccentricity, declination, expansion and contraction.

• Easy construction

EP JOINT is lightweight and compact, does not require packing, and has a loose flange, making it easy to install.

• Combined effect

By using EP JOINT, you can obtain vibration isolation effect and displacement absorption property at the same time.
