The MDPE Straight Joiner 20mm to 3/4" BSPF is a compression fitting that directly links a 20mm MDPE run to a 3/4" BSP female threaded connection. Targeted at tradespeople and installers, it provides a straightforward, reliable straight connection without special tools. MDPE fittings are chosen for durability, flexibility and chemical resistance, which suits water supply and irrigation work, as well as certain industrial piping scenarios. This straight joiner is designed to maintain flow in a straight line while providing a secure seal between MDPE pipe and threaded components. Key features

• Connection: 20mm MDPE pipe to 3/4" BSP Female thread (BSPF)
• Material: MDPE, with PN10 pressure rating for compatible piping systems
• Pressure rating: up to 10 bar (1 MPa / 145 psi) at standard testing conditions
• Seals: compression mechanism with an olive and nut to create a tight joint when properly installed
• Corrosion resistance: MDPE’s inherent resistance to common chemicals helps lengthen service life
• Durability: suitable for varied temperatures and mechanical stresses within its rated use
• Versatility: appropriate for water supply, irrigation and general MDPE piping projects

Why it matters in the field - Simple installation: a straight connector reduces fitting complexity in tight spaces and speeds up installs compared with more intricate configurations. - Cost efficiency: a single straight joiner can replace multiple components, lowering material costs on smaller builds and repairs. - Practical compatibility: designed to work with standard 20mm MDPE pipe and 3/4" BSP threaded accessories, allowing straightforward integration with pumps, taps and fixtures that use BSP threads. - Reliability: when installed to manufacturer guidance (cut square ends, clean and deburr, tighten the compression nut adequately), joints are designed to be leak-minimising under PN10 system conditions. Use case scenarios - Domestic cold-water mains extensions where a 20mm MDPE line needs to feed a 3/4" BSPF fixture - Irrigation mains that require a durable MDPE-to-thread adaptor in a straight run - Retrofit projects where existing MDPE piping meets threaded equipment without soldering or welding Compatibility and care - Ensure the system uses PN10 MDPE piping and that the connected equipment accepts 3/4" BSPF threads - Inspect joints after initial filling for leaks and re-tighten if needed, following the manufacturer’s guidelines - Use appropriate compression components and install per best practice to maximise long-term performance
