Compact manifold insert adapter engineered for easy, tool-free manifold assembly and quick valve servicing. The DURA 335-010 is a gray PVC Schedule 40 swivel x insert fitting designed for 1" nominal poly pipe and manifold systems that use O-ring seals.

  • Durable PVC Sch. 40 construction: Made from gray Schedule 40 PVC for reliable corrosion resistance and long service life in irrigation and outdoor manifold applications.
  • Swivel x insert connection: 1" swivel female connection mates to manifold ports while the 1" insert accepts poly pipe over the barb for secure line attachment.
  • O-ring sealed — no thread tape: Designed for O-ring sealing; do not use paste, pipe dope, or Teflon tape. Hand-tighten swivel for a serviceable, leak-resistant seal.
  • Easy installation & maintenance: Push 1" poly over the insert and clamp with an Oetiker or screw clamp; swivel design allows valve removal without disassembling the whole manifold.
  • Performance rating: Schedule 40 PVC construction and tested for typical irrigation pressures (commonly rated to 150 PSI at 73°F by suppliers; verify local system requirements before use).

This adapter is intended for manifold system use, irrigation, and other low-pressure piping where a removable, O-ring sealed connection is desired. Keep fittings clean during assembly, avoid lubricants that can harm O-rings, and clamp poly tubing securely. See the Special Piping Components catalog (linked in product documents) for full system compatibility, part references, and installation diagrams.
