Type MSA: The MSA is a completely new generation of highly flexible metal hose recently put into production using a fully automated assembly line. MSA hoses are designed to fit all common exhaust system pipe diameters.

Properties include:
• Acceptance of large axial, angular and/or lateral motion
• Best decoupling of engine vibration
• Horizontal or vertical mounting orientation
• Ends are free of lubricants and designed for accurate and smokeless welding into the exhaust system
• 100% tested and documented function and geometry
• Function remains constant over the life of the vehicle

Type SG: Type SG is a semi-self supporting design which may be a lower cost alternative to self-supporting decoupling joints:

Properties include:
•Acceptance of angular and axial motion
• Good decoupling of engine vibration
•Compact and symmetrical design
• Horizontal or vertical orientation - vertical when located
