High-quality compression fitting ideal for connecting 20mm MDPE pipe to a 1" BSP female threaded f...High-quality compression fitting ideal for connecting 20mm MDPE pipe to a 1" BSP female threaded fitting. Suitable for cold water systems, rated to PN16 pressure. Durable, corrosion-resistant, and easy to install—perfect for plumbing, irrigation, and industrial applications.
This B2C compression fitting is designed for plumbers, DIY enthusiasts, and industrial users needing to connect 20mm MDPE pipe to a 1" BSP female threaded fitting. Its key benefit is providing a secure, leak-free connection in cold water systems up to PN16 pressure. A minor caveat is its specific application for cold water only. It offers a durable, corrosion-resistant solution that is straightforward to install, making it ideal for various plumbing, irrigation, and industrial projects.
What is the maximum pressure rating for this fitting?
This fitting is rated to PN16, which corresponds to 16 bar or approximately 232 psi for cold water systems.
Can this fitting be used for hot water pipes?
No, this fitting is specifically designed and rated for cold water systems only. It is not suitable for hot water applications.
What type of pipe does the 20mm side connect to?
The 20mm side is designed to connect to standard 20mm MDPE (Medium Density Polyethylene) pipe, commonly used for water supply.
What does 'BSPF' mean in the product name?
BSPF stands for British Standard Pipe Female. This indicates the threaded connection is designed to accept a male BSP thread and has a specific thread form and pitch standard.
Do I need any special tools to install this fitting?
No special tools are required. You will need two wrenches (e.g., pipe wrenches or adjustable spanners) to tighten the compression nut, but no solvents, primers, or heat are necessary.
How do I ensure a leak-proof connection?
Ensure the pipe is cut square, clean, and fully inserted. Tighten the compression nut sufficiently according to standard practice for compression fittings to compress the ferrule onto the pipe and create a seal.
Troubleshooting
Fitting is leaking after installation.
Check that the MDPE pipe was cut square and inserted fully into the fitting. Ensure the compression nut and ferrule were correctly positioned and tightened sufficiently. The pipe may be damaged or out of round; try re-cutting the pipe or using a repair insert if necessary.
Difficulty inserting the pipe.
Ensure the end of the 20mm MDPE pipe is not deformed. If it is, trim off the damaged end. Make sure the compression nut and ferrule are slid back sufficiently to allow full pipe insertion.
Compression nut is difficult to tighten.
Ensure the threads are clean and free of debris. If the pipe is very stiff, slight warming with a heat gun (used cautiously and not in excess) might help make it more pliable, but this is rarely necessary for standard MDPE.
Pros and Cons
Pros
Durable and corrosion-resistant construction for long-term use.
Simple compression design allows for quick and easy installation without specialized tools.
Secure connection suitable for PN16 pressure ratings in cold water systems.
Versatile for a range of applications including plumbing and irrigation.
Reduces the need for multiple adaptors by directly connecting two different fitting types.
Cons
Only suitable for cold water systems; not rated for hot water applications.
Requires precise pipe preparation for a secure, leak-free seal.
Specific to 20mm MDPE and 1" BSP female threads, limiting universal compatibility.
Compression fittings can be bulkier than push-fit alternatives.
Setup, Compatibility & Care
Setup:
Ensure the 20mm MDPE pipe end is clean, dry, and cut square.
Carefully loosen the compression nut on the fitting.
Slide the compression nut onto the MDPE pipe, followed by the ferrule (or olive).
Insert the MDPE pipe fully into the fitting body until it stops.
Slide the ferrule down to the fitting body and hand-tighten the compression nut.
Using appropriate wrenches, tighten the compression nut a further 1 to 1.5 turns (refer to manufacturer's specific torque settings if available) to create a secure seal.
For the 1" BSP female threaded end, simply screw it onto the corresponding male threaded fitting, ensuring a tight connection.
Compatibility:
Pipe: Compatible with standard 20mm Medium Density Polyethylene (MDPE) pipe.
Thread: Compatible with 1" BSP (British Standard Pipe) female threaded fittings.
System: Suitable for cold water systems only.
Care:
Periodically inspect the fitting for any signs of damage or leakage, especially in underground installations.
Ensure connections remain secure. Overtightening is not necessary and can damage the fitting or pipe.
Clean exterior with a damp cloth; avoid abrasive cleaners.
