MDPE Straight Joiner 25mm to 1" BSPM is a compression fitting that adapts a 25mm MDPE pipe to a 1" BSP male thread, delivering a neat, straight inline connection for water, irrigation and industrial piping. Designed for on-site tradespeople, it offers a reliable seal without the need for specialist tools. Key benefits
- Pressure rating: PN10 MDPE fittings are rated up to 10 bar (approximately 1 MPa / 145 psi), suitable for typical domestic and light industrial systems.
- Material resilience: MDPE provides good chemical resistance and durability, helping protect against corrosion and long-term wear.
- Leak-free joints: When installed properly, compression connections are designed to form tight, reliable seals.
- Durability and versatility: Built to withstand temperature variations and mechanical stress, suitable for water supply, irrigation, gas distribution and certain industrial applications.
- Straight connection: The 25mm to 1" BSPM configuration supports direct, in-line runs without angle changes, reducing potential leakage points.
- Simple installation: No heat or solvent welding required; just tighten the compression sleeve onto the MDPE pipe and threaded festa on the BSP side. Ideal uses
- Domestic water supply lines bridging MDPE mains to appliances or manifolds
- Irrigation systems where 25mm MDPE pipes must join to a threaded fitting for valves or manifolds
- Light industrial pipes needing a straightforward 25mm to BSP connection
- Retrofitting or repairs where pipe ends are cut cleanly and threaded connections are preferred Installation notes
- Ensure MDPE pipe ends are cut square and deburred for a clean seal.
- Verify the 25mm pipe fits correctly into the compression sleeve and that the BSP male thread is clean and undamaged.
- Tighten the compression nut and check for leaks after commissioning. If leakage occurs, re-tighten within recommended torque range and inspect pipe ends. Specifications
- Fitting type: MDPE Straight Joiner compression fitting
- Connection: 25mm pipe to 1" BSP male thread
- Material: MDPE
- Pressure rating: PN10
- Applications: water supply, irrigation, gas distribution and industrial piping (where MDPE PN10 is suitable)

Deliveries must be signed for, please report any damages to us within 24 hours.
We offer all bricks with a tail lift offloading service, Please familiarise yourself with the information below.
Crane offloading is available as a premium service for some bricks.

All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.
If you'd prefer crane offloading rather than tail lift vehicle offloading for your brick order then this service is available for the majority of bricks that we sell. Charges are shown at checkout.
For deliveries of less than 6 packs then Taillift offloading is normally a more cost effective option
