Made in Japan
Manufacturer: Naigai Rubber Industry Co.,Ltd
Model: Pressure PF Type (large diameter )

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.

Operating pressure: 0.29MPa (3kgf/cm²) or lower
Negative pressure: -0.01MPa (-0.1kg/ cm²) or higher
Operating temperature: -30°C to +100°C (Cooling and heating water)
• Before use, check that maximum working pressure and maximum working temperature are within operational ranges.

Standard Dimensions and Allowable Displacements

• Weights with SS400 or JIS10K flanges (standard) mounted are indicated.
• Dimension allowances on installation are included in allowable displacements.
  (Allowable displacement = Dimension allowances on installation + Displacement under operation)
