Yes, both types are compatible
PEX EVOH pipes are fully compatible with push-fit and crimp fittings. The pipe's outer diameter matches standard PEX. The EVOH layer does not affect fitting compatibility. Example: standard fittings work perfectly.
Push-fit fitting compatibility
Push-fit fittings work with PEX EVOH pipes. The pipe inserts into the fitting easily. Internal teeth grip the pipe securely. PEX EVOH pipes accept push-fit connectors.
Crimp fitting compatibility
Crimp fittings also work with PEX EVOH pipes. A metal ring is crimped around the pipe. The crimp secures the pipe and fitting. PEX EVOH pipes can be crimped like standard PEX.
Clamp fitting compatibility
Clamp fittings are another option. A stainless steel clamp is tightened around the pipe. The clamp provides a secure connection. PEX EVOH pipes accept clamp fittings.
Outer diameter compatibility
The pipe has a standard PEX outer diameter. All standard PEX fittings will fit. The EVOH layer is internal and does not affect size. PEX EVOH pipes match standard fitting dimensions.
CRP and non-CRP fittings
Some fittings are compatible with PEX-AL-PEX (CRP). Others are for solid PEX. PEX EVOH pipes work with standard PEX (non-CRP) fittings.
Fitting standards
Fittings must meet ASTM F877 or ASTM F1807 standards. These cover PEX compression and push-fit fittings. PEX EVOH pipes comply with these standards.
Example: push-fit installation
A plumber uses PEX EVOH pipes for a new system. He connects them with push-fit fittings. The fittings grip the pipe securely. Example: a fast, tool-free installation.
Example: crimp fitting installation
A contractor uses PEX EVOH pipes in a large building. He uses crimp fittings for all connections. The fittings are fast and reliable. Example: a high-volume, efficient installation.
Manufacturer recommendations
Check the fitting manufacturer's compatibility list. Most list PEX EVOH as compatible. Follow the manufacturer's guidelines. PEX EVOH pipes are widely accepted.
Installation best practices
Cut the pipe squarely and deburr it. Ensure full insertion for push-fit fittings. Use the correct crimping tool for crimp fittings. PEX EVOH pipes require proper installation technique.
Final compatibility summary
PEX EVOH pipes are compatible with push-fit and crimp fittings. The outer diameter matches standard PEX. The EVOH layer does not interfere with fitting connections. Push-fit, crimp, and clamp fittings all work. Use fittings that meet ASTM standards. Always follow manufacturer guidelines. Proper installation ensures leak-free connections. PEX EVOH pipes offer full fitting flexibility. Example: a versatile pipe for any installation method.
