Flexible Pipe Connector - Expansion Joints

Super Flex Pipe Connectors

Super Flex expansion joints were designed after years of application experience. They are great for vibration & noise control.

Manufactured using thermostatically controlled heated hydraulic presses and redesigned moulds has resulted in expansion joints with higher operating pressures with greater safety factors. Nylon tire cord provides good carcass reinforcing and DuPont Nordel (EPDM) cover and liner excellent aging and temperature resistance.

Expansion Joint Features:

Mason flex has been sold without interruption for approximately 25 years. In this lastest improved version of these super flexible pipe connectors, the Kevlar reinforcement replaces nylon to greatly reduce elongation and to provide virtual insensitivity to high temperatures.


• Recommended for expansion and contraction
• Replaces expansion loops
• Compensates for misalignment and offset
• Protects from start-up and surge forces
• Vibration protection for piping and noise control
• Liner ribs to smooth water flow
• Installation cost reduction by eliminating gaskets, pipe alignment and quick connection
• Union fittings 20mm to 50mm
• Flanges (all types) from 40mm to 300mm
