Made in Japan
Manufacturer : Hachiken
Model : EL

Low reaction force expansion

The expansion has a low reaction force design, and the reaction force during displacement is smaller than the standard expansion (EA).

The Purpose

• Anti-vibration/sound insulation and absorption of misalignment of pipes made of low-strength materials such as PVC and FRP

Usage

• Connection of resin piping such as PVC

Standard specifications

• Maximum operating temperature : -10 to 60°C
• Maximum working pressure : See performance table
• Flange standard : JIS 10K
• Inner rubber material : EPDM

Structure and material

Part number	Name	Material
1	Inner rubber	EPDM
2	Reinforcing layer	Synthetic fiber
3	Body reinforcement layer	Steel wire or synthetic fiber
4	External rubber	EPDM
5	Flange	SS*

*Hot-dip galvanized flanges are standard.

Dimensions and performance table

* Please inquire separately about sizes from 550A to 1000A.

Option

* If this product is made into a rubber embedded specification (solid), the reaction force will increase significantly.

*Please inquire separately about 2 or 3 ridges.

<Caution>
Since this product has a larger thrust force when pressurized than general joints, if it is used for pipes with low strength such as those made of resin, the pipes may be damaged due to elongation. The use of safety bolts) is particularly strongly recommended.

<Remarks/Precautions>

• Please note that the maximum working pressure is lower than Expansion (EA).
• If necessary, use the control unit ( here ).
• Not manufactured for burying.
• If the fluid is gas, the maximum working pressure will be 1/2 of the above value.
• Please contact us for non-standard specifications (diameter, length, etc.).
• Due to the manufacturing method, the plating on the flange may be discolored or mottled, but this does not affect performance.
