A bellows-type rubber joint used where large expansion and contraction is required at low pressure. This product has the least axial reaction force among various rubber joints.

Feature

• Due to the bellows structure, the compressive reaction force in the axial direction is extremely small.
• Unlike general bellows, it is not sewn at all, so it is highly airtight.

The purpose

• Connection of piping with low pressure and large displacement.
• Connection of piping that requires low reaction force such as scales.

Usage

• Connection of vibrating feeders and automatic weighers in powder piping systems
• Blower anti-vibration/sound insulation
• Connection of places that are frequently removed, such as moving hoppers
• Absorption of expansion and contraction caused by the temperature of PVC piping
• Dust cover for cylinder rod

Standard specifications

• Maximum operating temperature : -10 to 60°C
• Maximum working pressure : -20kPa to 0.01MPa
• Flange standard : JIS 5K
• Rubber material : CR

Structure and material

*The standard flange is electrogalvanized.
