Support sleeves may be needed
PP Compression Fittings may require a support sleeve for thin-walled pipes. The ferrule compresses the pipe. Thin walls can collapse under compression. Example: a sleeve supports the pipe wall.
When sleeves are needed
Thin-walled pipes are more prone to collapse. A support sleeve prevents this. The sleeve is inserted into the pipe. PP Compression Fittings may require sleeves.
Support sleeve function
The sleeve provides internal support. It prevents the pipe from crushing. The ferrule compresses against the sleeve. PP Compression Fittings sleeves are important.
Sleeve material
Sleeves are typically made of plastic or brass. They fit inside the pipe. They support the pipe wall. PP Compression Fittings sleeves are available.
Example: thin-walled pipe installation
A plumber uses PP Compression Fittings with a thin-walled pipe. He inserts a support sleeve. The fitting installs without crushing. Example: a reliable connection.
Example: thick-walled pipe installation
A plumber uses PP Compression Fittings with a thick-walled pipe. No sleeve is needed. The pipe is strong enough. PP Compression Fittings work without sleeves.
Manufacturer recommendations
Always check the manufacturer's recommendations. Some may require sleeves. PP Compression Fittings should be installed per guidelines.
Sleeve benefits
Sleeves prevent pipe deformation. They ensure a uniform seal. They improve connection strength. PP Compression Fittings benefit from sleeves.
Sleeve installation
Sleeves are pushed into the pipe end. They fit snugly inside. The pipe is then inserted into the fitting. PP Compression Fittings installation is simple.
Cost and availability
Sleeves are inexpensive and available. They are sold by PP pipe manufacturers. PP Compression Fittings sleeves are easy to find.
Final sleeve summary
PP Compression Fittings may require support sleeves for thin-walled pipes. Sleeves prevent pipe collapse. Thick-walled pipes do not need sleeves. Always check manufacturer recommendations. PP Compression Fittings are versatile and reliable. Example: use sleeves when needed.
