What Sizes and Types of PPR Plastic Fittings Are Available
2025-12-09
When planning a modern plumbing or industrial piping system, selecting the right components is crucial for ensuring long-term performance and reliability. PPR Plastic Fittings, made from Polypropylene Random Copolymer, have become the gold standard for hot and cold-water installations due to their corrosion resistance, thermal insulation, and seamless joint integrity. At Besta, we specialize in manufacturing high-quality PPR systems engineered for durability and ease of installation. A common question we encounter from engineers, contractors, and DIY enthusiasts is: What sizes and types of PPR Plastic Fittings are actually available? This blog provides a detailed guide to our comprehensive product range.
Types of Besta PPR Plastic Fittings
Our catalog features a full spectrum of fittings designed for every connection need in a PPR pipeline system. The primary types include:
-
Couplings: For connecting two pipes of the same diameter in a straight line.
-
Elbows: Available in 90° and 45° angles to change the direction of the flow.
-
Tees: Equal and reducing tees to create branch connections.
-
Reducers: For connecting pipes of different diameters.
-
End Caps: To seal the end of a pipe.
-
Union Nuts: Allow for easy disconnection and maintenance of the pipeline.
-
Ball Valves: Besta integrates durable PPR ball valves for flow control, with brass or full PPR internals.
Besta PPR Fittings: Standard Size Chart
PPR pipes and fittings are dimensioned according to their outer diameter (OD). Below is a table of our standard sizing, which conforms to international norms.
| Nominal Size (DN) | Outer Diameter (mm) | Common Application Scope |
|---|---|---|
| 20 | 20 mm | Residential water inlets, branch lines |
| 25 | 25 mm | Main bathroom feeds, radiator connections |
| 32 | 32 mm | Main house supply lines, commercial installations |
| 40 | 40 mm | Larger residential mains, industrial water lines |
| 50 | 50 mm | Main building risers, drainage applications |
| 63 | 63 mm | Industrial and large-scale commercial mains |
PPR Plastic Fitting FAQ
Q: Are all PPR Plastic Fittings compatible with any brand of PPR pipe?
A: While PPR systems are standardized by outer diameter, we highly recommend using Besta fittings with Besta pipes. This ensures perfect material compatibility and identical thermal expansion coefficients, guaranteeing a leak-proof fusion weld and system longevity.
Q: What is the pressure rating for Besta PPR fittings?
A: Besta PPR Plastic Fittings are classified by pressure ratings, commonly PN20 (rated for 20 bar at 20°C) and PN25 (rated for 25 bar at 20°C). PN25 fittings have a thicker wall and are specifically designed for high-temperature applications like central heating systems.
Q: Can PPR Plastic Fittings be used for outdoor installations?
A: PPR is resistant to chemicals and weathering, but prolonged direct exposure to UV radiation can degrade the material. For outdoor use, Besta recommends protective insulation or using our specially formulated, UV-stabilized PPR products to ensure optimal service life.
