Designed to terminate or test piping systems with absolute reliability, the Series 517 HDPE Blind Flange with Female NPT combines hydraulic compression technology and a reinforced barbed design for leak-free performance. Ideal for industrial, municipal, and utility applications, this fitting ensures long-term integrity under pressure fluctuations and thermal stress. Available in sizes from 0.5" to 2" NPT, it meets ANSI/ASME B1.20.1 standards and includes a compression ring for added stability.

Key Features & Benefits

  • Blind Flange Functionality: Seals pipe ends securely while allowing future system expansion or pressure testing.
  • Pressure-Activated Seal: Multi-level barbs tighten under internal pressure, preventing leaks even during thermal contraction.
  • Lead-Free Materials: C954 Bronze option complies with environmental and potable water safety standards.
  • 50-Year Performance: Built with a 2:1 safety factor at 73.4°F, certified to ASTM 1598/1599 and ARRA requirements.

Technical Specifications

  • Sizes: 0.5”–2” NPT (ANSI/ASME B1.20.1 compliant).
  • HDPE Pipe: ASTM D3350 (PE3408/PE4710), F714, D3035. Tensile strength: 3,200–3,500 psi; ESCR ≥5,000 hours (zero failures).
  • Melt Index: ≤0.15 g/10 min (ASTM D1238).

Installation Guidelines

  • Use smooth-jawed or Poly-Cam wrenches—avoid pipe wrenches to prevent damage.
  • Apply Teflon tape or pipe sealant to threads for airtight connections.
  • Pressure-test joints before backfilling; compact soil to avoid shifts.
  • Follow Plastic Pipe Institute’s butt fusion procedures for HDPE welds.

Material & Compliance

  • Fittings: 304/316 Stainless Steel (ASTM A249/A269) or lead-free C954 Bronze.
