The NDS FLO-LOCK 733-10 PVC Gripper Adapter provides a durable, leak-resistant connection between 1 in. IPS spigot pipe and 1 in. SDR-9 CTS tubing. Designed for irrigation, plumbing, pool & spa, and repair applications, this adapter installs quickly without solvent welds and helps reduce pull-out and leaks where pipe movement may occur.

  • Leak-resistant gripper design: Steel gripper and EPDM O-ring form a secure seal and reduce the chance of pull-out.
  • Durable materials: Injection-molded PVC body with steel gripper; manufactured to ASTM D-2737 material specifications for long service life.
  • Easy installation: Compression-style fitting for SDR-9 CTS pipe installs without glue; includes stiffener and steel gripper for immediate use.
  • Wide applications: Use for irrigation, plumbing repairs, pool & spa connections, and other water service lines.
  • Technical performance: Designed for 1 in. nominal pipe, SCH 40 dimensions; rated for typical service pressures and built to common industry standards.
  • Certifications & documentation: UPC listed, NSF/ANSI 61 and IAPMO compliant; technical specification sheet available.

Each adapter ships ready-to-install with the internal stiffener and gripper components in place. For system design, reference the NDS technical specification sheet (part 733-10) for detailed dimensions, working pressure, and installation guidance. Replace gripped fittings if the gripper or O-ring shows wear to maintain a leak-free connection.
