PPR Tube Fitting

Plastic PPR fittings have become an extremely popular option for both residential and commerical building plumbings in recent years. PPR fittings have a wide range of applications in fields like plumbing, HVAC, water supply, fire protection systems, and more.

PPR piping systems are comprised of plastic PPR fittings, pipes, and valves. The fittings join and connect the PPR pipes, while the valves control flow. PPR fittings are offered in a range of sizes, from 20mm to 160mm diameter. They are used for both pressure and drainage applications across a variety of industries.

Compared to other plastic piping options like PVC, CPVC, and PB, PPR offers some unique advantages:

• Flexible and fatigue resistant - PPR can handle repeated stress and bending without cracking or breaking. This makes it ideal for earthquake-prone areas.
• Heat fusion connections - PPR fittings are joined together using heat fusion rather than glues or cement. This creates smooth, consistent, reliable joints.
• Corrosion and chemical resistant - PPR holds up exceptionally well to chemicals, acids, bases, and salts. It won't corrode over time.
• Thermal stability - The material retains its strength and structure across a wide temperature range from freezing to 95°C.
• Low hazards - PPR is non-toxic and fully recyclable at the end of its lifespan. Installation doesn't require any dangerous glues or solvents.

There are many different types of PPR fittings available to meet varied piping system needs:

Elbow fittings are used to create 90° turns in PPR piping runs. They are available in a wide array of sizes and configurations:

• 90° elbows
• 45° elbows
• Reducing elbows
• Long radius elbows
• Street elbows (short radius)

45° and long radius elbows reduce turbulence and resistance for improved flow. Reducing elbows transition from one pipe size to another.

Tees are used to branch off PPR piping in two directions. They come in:

• Straight tees - the run is the same size as the branches
• Reducing tees - the branches are smaller than the run dimension

End caps can be used on tee branches for temporary closures.

Couplings are short fittings used to join two pieces of pipe. Common types include:

• Straight couplings
• Reducing couplings
• Step-down couplings
• End stop couplings
• Transition couplings

Couplings make the PPR system modular and adjustable.

Adapters connect PPR components to different types of pipe like PVC, steel, or copper. Options include:

• Union adapters
• Flange adapters
• Threaded adapters
• Socket end adapters

Adapters allow integration of PPR into diverse piping systems.

Unions act as disconnect points, allowing sections of piping to be detached. They have threaded ends to connect pipes.

These fittings are used to permanently or temporarily seal off the end of a pipe. Varieties include:

• End caps
• Flange caps
• Round plugs
• Square head plugs

End caps can seal off a tee branch until needed.

Unlike a standard reducer fitting, eccentric reducers have an offset in the centerline of the fitting. This allows the top and bottom of the piping run to remain aligned when changing sizes.

Wyes are Y-shaped fittings with all three openings at 120° angles. They allow a third connection point.

PPR fittings don't just connect pipes together - they are engineered to perform some very important roles.
