PVC Pipe Fittings

What Are PVC Fittings?

PVC fittings are the parts that join PVC (polyvinyl chloride) pipe into a complete working system. They come in many types and sizes for different jobs, and choosing the right, good-quality fitting matters for the performance and life of the whole line. Fittings change pipe direction, branch lines, reduce pipe size and connect pipe to other equipment such as valves and pumps.

Types of PVC Fittings

Each type of PVC fitting has its own shape and use:

• PVC couplings: join two pipes of the same size in a straight line.
• PVC elbows: change the direction of the line, in 45 and 90 degree versions.
• PVC tees: split one line into two, or merge two lines into one.
• PVC crosses: split one line into three.
• PVC caps: close the end of a pipe.
• PVC ball valves: open and shut off flow in the line.
• PVC nipples: join two fittings that have female threads.
• PVC threaded plugs: seal a threaded opening.
• PVC pipe clips: fix PVC pipe to a wall or structure.
• PVC hose tail adapters: connect a hose to PVC pipe.
• PVC unions: join pipe where the joint needs to come apart easily.
• PVC flanged short pipes: connect PVC pipe to equipment with a flange.
• PVC puddle flanges and waterproof sleeves: used where water must not leak through a wall or slab.
• PVC S-traps, P-traps and U-traps: odor traps for drainage systems.

There are also specialty PVC fittings designed for particular jobs.

Material and Manufacture

PVC fittings are made from polyvinyl chloride, a strong, chemical-resistant and lightweight plastic. Most are injection molded, which gives accurate dimensions and a smooth finish. Sizes run from small, such as 1/2 inch (4 hun) fittings, up to large diameters.

How to Choose PVC Fittings

When buying PVC fittings, consider:

• Size: match the fitting to the size of the PVC pipe.
• Type: pick the fitting type that suits the job.
• Standard: choose fittings certified to TIS for reliable quality.
• Manufacturer: buy from trusted makers such as SCG Elephant, Thai Pipe, DSAI, EUROX and WATER FLOW.

Use and Installation

Install PVC fittings carefully to get a strong, leak-free line. The usual steps are:

• Clean the pipe end and the inside of the fitting.
• Apply PVC solvent cement to the pipe end and inside the fitting.
• Push the pipe fully into the fitting.
• Wipe off excess cement.

Avoid using PVC fittings with very hot liquids or strongly corrosive chemicals. Inspect fittings regularly and replace any that show cracks or damage.

PVC Fittings and PE Pipe

PE pipe can be joined to PVC with special transition fittings designed for different pipe materials. These often include metal or other plastic parts so the PE and PVC pipe join tightly without leaks.

PVC Fitting Sizes

PVC fittings come in a wide range of sizes, from small sizes for household plumbing to large sizes for industrial work. Common sizes are 1/2, 3/4, 1, 1-1/4, 1-1/2, 2, 2-1/2, 3, 4, 5, 6, 8, 10 and 12 inches.

Applications

PVC fittings are used in many kinds of work, such as:

• Plumbing in homes and buildings
• Waste water drainage
• Farm irrigation
• Industrial piping
• DIY projects such as furniture built from PVC pipe

PVC Hose Tail Adapters

A PVC hose tail adapter connects PVC pipe to a hose. It is often used where a flexible connection is needed, such as garden watering systems or connecting a hose to a water pump.

PVC Unions

1-inch and 2-inch PVC unions join PVC pipe where the line needs to come apart easily, which helps with maintenance and repair.
