Plastic Fittings
Precision injection moulded plastic hose barbs, threaded pipe nipples, elbows, and quick-connect fluid couplers. Moulded in FDA compliant Polypropylene, chemical-grade PVDF, and tough Nylon for chemical handling, beverage dispensing, and medical tubing lines.
Types & Configurations of Plastic Fittings
Multi-Tier Hose Barb Connectors
Engineered sharp barb geometry providing high burst grip on flexible silicone and PVC tubing.
Moulded NPT & BSP Threaded Adaptors
Hex nipples, reducing bushings, and female sockets with clean flash-free precision threads.
Push-In Pneumatic Tube Fittings
Acetal bodied fittings with internal stainless gripper teeth and NBR O-ring sealing.
Sanitary Tri-Clamp Plastic Ferrules
Moulded PVDF and PP sanitary ferrules for single-use pharmaceutical bioprocess lines.
Y & T Fluid Manifold Splitters
Smooth internal bore flow dividers minimizing pressure drop in coolant and washing circuits.

Material Selection & Properties
We offer specialized compound formulations tailored to chemical media, thermal extremes, static deflection, and dynamic fatigue requirements. The best material depends on your operating environment and required service life.
| Material / Polymer | Key Engineering Properties | Recommended Applications & Considerations |
|---|---|---|
| Nylon 6 / 66 (Polyamide) | High tensile strength, toughness, good sliding properties | Gears, wear pads, wire rope pulleys, bushings |
| POM (Acetal / Delrin) | High dimensional stability, zero moisture absorption | Precision gears, valve seats, fuel sender parts |
| UHMW-PE (Ultra-High Molecular) | Extremely low coefficient of friction (0.10), zero wear | Conveyor wear strips, chute liners, chain guides |
| HDPE / Polypropylene | Chemical resistance to acids & alkalis, food contact | Chemical tank flanges, pipe fittings, plating barrels |
| Polycarbonate (PC) | Optically clear, high impact strength (unbreakable) | Machine safety guards, instrument sight glasses |
