Series 517 HDPE Blind Flange with Female NPT
Series 517 HDPE Blind Flange with Female NPT — Product Overview
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).
