Made in Japan
Manufacturer: Naigai Rubber Industry Co.,Ltd
Model: Pressure PL 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: 0.98MPa (10kgf/cm²) or lower

Negative pressure: -0.01MPa (-0.1kgf/cm²) or higher

Operating temperature: -30°C ~+90°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 AC7A or JIS10K flanges mounted are indicated.
• Dimension allowances on installation are included in allowable displacements. (Allowable displacement = Dimension allowances on installation + Displacement under operation )

Product features

1. Stable durabililty with a combination of strong reinforcing fibers and reinforcing steel wires.
2. Excellent chemical resistance and weather resistance by employing EPDM as internal and external rubber surface material.
3. Allowable displacement larger than that of P type products.
4. Excellent installation workability with loose flange.

Product applications

1. Absorption of expansion, contraction and displacement of low-pressure piping.
2. Absorption of expansion, contraction and displacment of piping for water supplies and sewers.
3. Protecting piping joints around water tanks.

Considerations for handling

• This product may not be used with oils and solvents.
• This product may not be used with piping for hot water and swimming pool water circulatory system.
