HDPE Fabricated Fittings

HDPE Fabricated Fittings

Plastic Fusion Fabricators builds custom HDPE fabricated fittings for industrial, municipal, and environmental piping systems that demand strength, chemical resistance, and long-term performance. We fabricate elbows, tees, wyes, reducers, crosses, branch saddles, and flanged adapters from pressure-rated HDPE pipe stock — fusion-welded by certified technicians and built to the exact configuration your system requires.

Fabricated fittings differ from molded fittings in an important way: rather than being injection-molded in standard sizes, fabricated fittings are built from segments of HDPE pipe, cut and fusion-welded into the angles, branches, and transitions a project needs. This makes fabrication the right approach for large-diameter fittings, non-standard angles, custom configurations, and any application where a molded fitting doesn’t exist or doesn’t fit. When the fitting you need isn’t on a shelf, it gets fabricated.

With 40+ years fabricating HDPE and an in-house fabrication shop, Plastic Fusion delivers fittings engineered to match your pipe’s pressure rating and dimensions — fused, tested, and shipped job-ready to integrate cleanly with your piping system.

Fittings We Fabricate

• Elbows — mitered elbows in standard and custom angles
• Tees and crosses — equal and reducing configurations
• Wyes and laterals — branch connections at custom angles
• Reducers — concentric and eccentric transitions between pipe sizes
• Branch saddles — for connections to existing pipe runs
• Flanged adapters and stub ends — for connection to valves, equipment, and flanged systems
• End caps and closures
• Custom transitions — specialty configurations built to drawing

Why Fabricated Fittings

• Large-diameter capability — fabricated fittings serve sizes where molded fittings aren’t available
• Custom angles and configurations — built to your exact geometry, not limited to standard molded shapes
• Pressure-matched — fabricated from the same pressure-rated pipe stock as your system
• Monolithic fusion joints — fused construction with no mechanical leak paths
• Made to spec — the fitting your drawing calls for, when a standard fitting won’t work

Applications

• Water and wastewater treatment plant piping
• Biogas and landfill gas collection systems
• Municipal water distribution and force mains
• Industrial process conveyance
• Mining process water and slurry piping
• Environmental containment and collection systems

HDPE Fabricated Fittings FAQs

What are HDPE fabricated fittings?

HDPE fabricated fittings are pipe fittings — elbows, tees, wyes, reducers, and branch connections — built by cutting and fusion-welding segments of HDPE pipe into the required configuration. Unlike molded fittings, which are injection-molded in standard sizes, fabricated fittings are custom-built, making them ideal for large diameters, non-standard angles, and configurations that molded fittings don’t cover.

What is the difference between fabricated and molded HDPE fittings?

Molded fittings are mass-produced by injection molding in standard sizes and configurations — economical for common small-to-mid-diameter fittings. Fabricated fittings are built from pipe stock, cut and fusion-welded into the needed shape. Fabrication is the right choice for large-diameter fittings (where molds don’t exist), custom angles, reducing configurations, and specialty geometries. Plastic Fusion fabricates fittings to match your system’s exact pressure rating and dimensions.

What types of HDPE fittings can you fabricate?

We fabricate elbows (standard and custom angles), tees and crosses (equal and reducing), wyes and laterals, concentric and eccentric reducers, branch saddles, flanged adapters, stub ends, end caps, and custom transitions. If your piping design calls for a fitting that isn’t available as a standard molded part, we fabricate it to your drawing.

Are fabricated fittings as strong as the pipe?

Yes. Fabricated fittings are built from the same pressure-rated HDPE pipe stock as your system and joined with fusion welds that are as strong as the parent material. Properly fabricated and fused fittings carry the same pressure rating as the pipe they connect, with monolithic joints that have no mechanical leak paths.

Can you fabricate large-diameter fittings?

Yes. Large-diameter fittings are one of the primary reasons projects use fabricated rather than molded fittings — molded fittings often aren’t available in larger sizes. We fabricate large-diameter elbows, tees, reducers, and custom fittings from HDPE pipe stock. Contact us with your size and configuration requirements.
