PVC Fitting Types

U-PVC Fittings

U-PVC fittings are elbows, tees, sockets, reducers and transition parts joined by solvent cement or thread on unplasticised rigid PVC (U-PVC) pipe lines.

They are used on cold clean water, pool and water treatment plants, irrigation mains and process lines carrying many chemical fluids. They fall into two main groups, solvent cement and threaded; sizes and pressure class are supplied depending on the model.

Technical Data

Material	U-PVC (unplasticised rigid PVC) (depending on model)
Connection	Solvent cement or thread
Fitting types	Elbow, tee, reducing tee, cross, socket, reducer, end cap, stub flange, union, nipple
Sizes	Depending on model, please ask
Pressure class	Depending on model (confirmed by manufacturer sheet)
Operating temperature	Cold water (not for hot water), limit depending on model
Standard	Depending on model (confirmed by manufacturer sheet)
Chemical resistance	Confirmed from the manufacturer table per fluid
Flange transition	With a socket or threaded stub flange
Detachable joint	With a union
Compatibility	U-PVC pipes of the same size system
Colour	Depending on model (grey common)

Material Options

Part	U-PVC (pressure)	PVC drainage	PPR
Body	Unplasticised rigid PVC	PVC	PP-R
Connection	Solvent cement or thread	Gasketed socket or solvent cement	Socket fusion welding
Pressure	Pressure lines (PN depending on model)	Non-pressure (gravity) lines	Pressure lines
Hot water	Not suitable	Not suitable (depending on model)	Suitable
Use	Cold clean water, pools, chemicals	Soil and rainwater	Hot and cold domestic water

Which material? U-PVC is for cold water and chemical lines; PPR should be used on hot domestic water and heating lines, and PVC drainage fittings on non-pressure soil lines.

How to Choose?

Determine the pipe sizeMeasure the U-PVC pipe outside diameter.
Choose the connection methodUse solvent cement on permanent lines and threaded types at valve transitions.
Check the fluidConfirm resistance from the manufacturer table on chemical lines.
Plan detachable pointsPlace unions or stub flanges before pumps and valves.
