Yes, they are universally compatible
PEX Sliding Fittings are compatible with PEX-A and PEX-B pipes. They grip the pipe's outer diameter. The fitting design works for both types. Example: use them with any PEX pipe.
PEX-A compatibility explained
PEX-A is the most flexible PEX type. The fittings grip it securely. The pipe deforms slightly under the ring. PEX Sliding Fittings work perfectly with PEX-A.
PEX-B compatibility explained
PEX-B is the most common PEX type. It has a slightly stiffer wall. The fittings still grip it securely. PEX Sliding Fittings are ideal for PEX-B.
Outer diameter consistency
Both PEX types have the same outer diameter. This is controlled by ASTM standards. The fittings rely only on the outer diameter. PEX Sliding Fittings are universally sized.
Example: mixing PEX types
A system uses PEX-B for mains and PEX-A for branches. PEX Sliding Fittings connect both types. The same fitting works for both. Example: a seamless mixed system.
Example: repair with different PEX
A PEX-A pipe is repaired with a sliding fitting. The fitting works perfectly. PEX Sliding Fittings are type-independent. Example: a simple repair.
Manufacturer testing
Manufacturers test fittings with all PEX types. They confirm compatibility. PEX Sliding Fittings are certified for all types.
Installation procedure is identical
The installation procedure is the same for all types. No adjustments are needed. PEX Sliding Fittings are easy to use.
Pipe support inserts
PEX-A may require support inserts to prevent collapse. PEX-B generally does not. PEX Sliding Fittings work with or without inserts.
Temperature and pressure ratings
All PEX types have the same temperature and pressure ratings. PEX Sliding Fittings match these ratings.
Final compatibility summary
PEX Sliding Fittings are compatible with PEX-A and PEX-B. The outer diameter is identical for both types. The fitting grips the outside of the pipe. Installation is the same for both types. PEX Sliding Fittings are universally compatible. Example: use them with any PEX pipe.
