Rubber Expansion Joints
There are many types of flexible pipe connectors and expansion joints produced by Mason Industries. This page gives a brief overview with links to more specific product details.
When fluid is pumped around a system, it normally happens as a series of pulses rather than a smooth flow. The nature and frequency of the pulses depends on the pump, but they can have undesirable effects.
Pulses can easily be carried around the building through the pipe network, possibly causing noise and/or vibration problems and sometimes the energy is sufficient to cause damage to the pipes over time.
Varieties of connector
The fluid pressure increases as the pulse passes through the connector. This expands the rubber arch or arches of the connector outwards, absorbing energy. This greatly reduces or eliminates the pulse. Flexible connectors are therefore most commonly used on the inlet and outlets of pumps and similar equipment.
Mason U.K. can supply a great variety of flexible connectors. Some of the options available are:
• A variety of elastomers to suit the application, including natural rubber, Butyl, EPDM, neoprene, Teflon and nitrile.
• Reinforcement can be Nylon or stronger materials such as Kevlar
• Some of our connectors (Safeflex) have steel rings rather than wire to prevent the carcass pulling out – unique to Mason products. No Safeflex connector has ever failed in service.
• Ductile iron and a variety of stainless steel grade flanges available.
Total support
Mason U.K. can provide your project with full support, whether aiding with product selection or design, or providing calculations and drawings for pipeline modelling.

Super Flex Pipe Connectors
Super Flex expansion joints were designed after years of application experience. They are great for vibration & noise control.
Safe Flex Pipe Connectors
The Safeflex flange uses a fully encapsulated square section ring instead of cables. This greatly reduces the risk of failure and eliminates the need for control rods/cables at normal working pressures.
Masonflex Expansion Joints
Masonflex has been sold without interruption for approximately 25 years. In this latest improved version the Kevlar® reinforcement replaces Nylon to greatly reduce elongation and to provide virtual insensitivity to high temperatures.
Mercer Connectors
Mercer Rubber Company, established in 1866, is the oldest U.S. manufacturer of rubber expansion joints, flexible duct connectors and industrial hose. All connectors are hand built to the highest standards.
