IFAN OEM Available PEX-EVOH Pipes

Both methods are available

PEX-EVOH pipes can be installed with mechanical fittings. Heat fusion is also a valid option. The choice depends on the pipe’s intended use. Example: mechanical fittings for repairs and fusion for new systems.

Heat fusion method

Heat fusion is the most reliable joining method. It creates a permanent, leak-free bond. The pipe and fitting are heated and fused together. PEX-EVOH pipes fusion weld like standard PEX.

Mechanical fittings for PEX

PEX compression fittings are widely available. Crimp and clamp fittings also work with PEX. Push-fit fittings are compatible with PEX pipes. PEX-EVOH pipes accept all standard PEX mechanical fittings.

Fitting compatibility

The pipe’s outer diameter matches standard PEX. All standard PEX fittings will work. No special fittings are required. PEX-EVOH pipes are fully compatible with PEX fittings.

Advantages of heat fusion

Heat fusion provides the strongest joint possible. The joint is as strong as the pipe itself. No potential for leaks from O-rings. Cross-linked Polyethylene – Ethylene Vinyl Alcohol Copolymer pipes are permanently joined with fusion.

Advantages of mechanical fittings

Mechanical fittings are quick and easy to install. No special fusion tools are required. Repairs and modifications are simpler. PEX-EVOH pipes can be modified with mechanical fittings.

EVOH layer effect on fusion

The EVOH layer is a middle barrier layer. Fusion welding joins the outer PEX layers. The EVOH layer does not affect the fusion process. PEX-EVOH pipes fusion weld like standard PEX.

Example: new construction installation

A plumber is installing a new heating system. He uses heat fusion for all joints. Cross-linked Polyethylene – Ethylene Vinyl Alcohol Copolymer pipes are fused for maximum reliability. Example: a permanent, leak-free installation.

Example: emergency repair

A pipe bursts in an existing system. The plumber uses a compression fitting. Cross-linked Polyethylene – Ethylene Vinyl Alcohol Copolymer pipes accept the mechanical fitting easily. Example: a quick, effective repair.

Example: DIY installation

A homeowner installs a new underfloor heating system. He uses push-fit mechanical fittings. Cross-linked Polyethylene – Ethylene Vinyl Alcohol Copolymer pipes are easy to connect with these fittings. Example: a simple DIY project.

Manufacturer recommendations

Most manufacturers recommend heat fusion for permanent systems. Mechanical fittings are acceptable for repairs. Follow the manufacturer’s guidelines. PEX-EVOH pipes can be installed either way.

Final installation summary

PEX-EVOH pipes can be installed with both mechanical fittings and heat fusion. Heat fusion provides the strongest permanent joint. Mechanical fittings are quick and easy for repairs. The EVOH layer does not affect fitting compatibility. Choose heat fusion for new construction and permanent systems. Choose mechanical fittings for repairs and modifications. Cross-linked Polyethylene – Ethylene Vinyl Alcohol Copolymer pipes offer flexibility in installation methods. Example: a versatile pipe for any installation need.
