Series 503 45 Degree with Transition

Engineered for durability and reliability, the Poly-Cam Threaded Transition Fitting seamlessly bridges high-density polyethylene (HDPE) pipes with threaded systems. Using advanced hydraulic compression technology, this multi-level mechanical fitting ensures a robust, leak-proof seal—even under extreme pressure fluctuations. Ideal for industrial, municipal, and commercial applications, it combines innovative design with compliance to rigorous global standards.

Key Features

• Pressure-Activated Sealing: Multi-level barbs tighten under pressure, enhancing connection strength while preventing leaks during thermal shifts or system relaxation.
• 50-Year Design Life: Built to handle HDPE pressure ratings with a 2:1 safety factor at 73.4°F (23°C), ensuring decades of reliable service.
• Wide Size Range: Available in 0.5” to 8” NPT sizes, compliant with ANSI/ASME B1.20.1-2013 threading standards.
• Material Flexibility: Choose from carbon steel (A53/A106), stainless steel (Type 304/316), ERW pipe, or lead-free C954 aluminum bronze.

Technical Specifications

• Standards Compliance: Exceeds ASTM 1598, ASTM 1599, ARRA, NSF 61, FDA 175.300, AWWA, UL 262, and FM 1120/1130.
• HDPE Compatibility:
  • ASTM D-3350 (PE 3408/PE 4710), ASTM F714, ASTM 3035.
  • Density ≥0.955 g/cm³ | Tensile Strength: 3,200–3,500 psi.
  • Environmental Stress Crack Resistance (ESCR): 5,000+ hours (ASTM D1693).

Installation Best Practices

• For HDPE Connections: Follow Plastic Pipe Institute’s butt fusion welding procedures.
• For Threaded Ends:
  • Use Teflon tape or sealant; avoid pipe wrenches (strap wrenches only).
  • Tighten with two wrenches to prevent ovality or damage.
  • Pressure-test before backfilling and compact soil carefully to avoid shifts.

Materials & Quality Assurance

• Threaded Fittings: Corrosion-resistant epoxy coating (IF 194T Red Iron Oxide) on carbon steel; stainless steel and lead-free bronze options available.
• Certifications: NSF 61, FDA 175.300, AWWA C116/C213, UL 262, FM 1120/1130.
