A compact MDPE pipe fitting kit designed for water supply and irrigation runs, built for tradespeople and hands-on installers who want a straightforward straight connection with built‑in flow control. It combines reliable MDPE joins with a purpose‑built inline valve and a brass adaptor for versatile 19mm connections.
What’s included
- 1 x MDPE Straight Joiner 20mm – ¾” BSPF (MDPESTR20-34BSPF)
- 1 x In-Line Valve ¾” BSPM (HCV34BSPM001BLACK)
- 1 x Brass Adaptor 3/4" BSPF - 19mm (BR-TC19B-34BSPF)
Key features and benefits
MDPE fittings are chosen for their durability, flexibility and chemical resistance, making them suitable for water supply, irrigation and light industrial use. The 20mm straight joiner provides a direct, in‑line connection between MDPE pipes, with a ¾" BSP female thread to mate with the inline valve and brass adaptor. The inline valve uses a ¾" BSP male inlet/outlet and a smooth, soft‑touch turn to regulate flow with minimal effort—helpful when you’re balancing irrigation zones or isolating a section for maintenance. The brass adaptor converts 19mm pipe to a ¾" BSP connection, expanding the kit’s compatibility with existing 19mm systems.
Performance and compatibility
- Pressure rating: MDPE PN10 fittings designed to withstand up to 10 bar (around 145 psi), appropriate for typical domestic water and irrigation systems.
- Materials: MDPE components deliver chemical resistance and durability in outdoor and exposed environments; the inline valve body is a robust plastic construction, chosen for lightness and corrosion resistance.
- Seal and installation: the kit uses threaded BSP connections and compression-type interfaces that offer reliable seals when correctly assembled; no specialist equipment is required beyond standard hand tools and wrenches.
Practical use cases
- Connecting a 20mm MDPE feed to a 19mm irrigation run with a convenient shut‑off point at the valve.
- Isolating a section of a temporary or permanent garden water line for maintenance without dismantling the whole run.
- Retrofits where 19mm pipework must tie into a 20mm MDPE main with a simple, leak‑tight adaptor.
Tip from the trades: ensure ends are clean and cut square, tighten BSP connections firmly but avoid overtightening on plastic components. This kit offers a pragmatic, space‑saving solution for plumbing and irrigation setups where direct, straight runs and reliable control matter.
