Overview
The EPDM 9175K58 expansion joint is a single-arch TYPE-EE rubber compensator engineered for industrial hydraulic, pneumatic, and general piping applications. This 6-inch (150mm) unit features EPDM elastomer construction with reinforced flanges rated at 150 lbs, making it suitable for moderate-pressure service in systems requiring vibration isolation and thermal movement compensation.
Key Features
- EPDM rubber body with polyester or nylon cord reinforcement for durability
- 6-inch (150mm) nominal bore with 150 lbs flange rating
- TYPE-EE single-arch design for axial, lateral, and angular deflection
- Floating flange ends compatible with standard ANSI Class 150 flanges
- Reduces vibration, shock, and noise transmission in piping systems
- Accommodates thermal expansion and contraction without gaskets

Typical Applications
The EPDM 9175K58 expansion joint is widely used in:
- Pump discharge lines and motor-driven circulation systems
- HVAC chilled and hot water piping with thermal fluctuations
- Industrial blower packages and compressor discharge lines
- Vibration-sensitive equipment requiring noise isolation
- Water treatment, chemical processing, and general utility piping
- Systems requiring flexible connections between different pipe materials
Compatibility & Replacements
Compatible With
- ANSI Class 150 flange connections (6-inch DN150)
- Standard carbon steel and stainless steel piping systems
- Hydraulic, pneumatic, and water circulation systems
- Industrial pump and blower assemblies
- Systems rated for 150 psig or less working pressure
Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. Standard 6-inch ANSI Class 150 EPDM expansion joints with similar TYPE-EE single-arch configuration may be interchangeable, but flange bolt hole patterns and exact pressure ratings must be confirmed.
Works With
- Standard pipe guides and anchor points per installation best practices
- Limit rod sets (sold separately) to prevent over-extension
- ANSI B16.5 Class 150 flanged systems
- Common bolt sizes: 3/4-inch bolts with 7/8-inch hole dia.
