Product Information
Full details
The B&Q Compression Straight Fitting (15mm x 3/4" BSP Male) is designed for professional plumbers and DIY enthusiasts needing a reliable, leak-proof transition between 15mm piping and 3/4" threaded components. It offers the key benefit of a solder-free, compression-based installation that saves significant time during pipework repairs or upgrades, though users should note that the brass threads require careful alignment to prevent cross-threading during the initial installation.

FAQs
Does this fitting require soldering?
No, this is a compression fitting designed for mechanical installation using wrenches.
Can I use this for gas piping?
Yes, this fitting is suitable for gas systems, provided it is installed in accordance with local building and safety regulations.
What tools do I need for installation?
You will need two adjustable wrenches: one to hold the body of the fitting and one to tighten the nut.
Is this fitting reusable?
While the brass body is reusable, it is recommended to replace the olive if the fitting is disassembled, as the olive deforms to create the seal.
Will this fit plastic piping?
Compression fittings are primarily designed for copper pipe; using them on plastic pipe may require a specific pipe insert to maintain the structural integrity of the seal.
Troubleshooting
Fitting is leaking at the compression nut
Tighten the nut by another quarter turn. If the leak persists, disassemble and inspect the olive for deformation or debris.
Difficulty threading the 3/4" BSP male end
Ensure the threads are aligned perfectly before turning. Do not force, as this can cause cross-threading; back it out and restart carefully.
Pipe keeps pulling out of the fitting
Verify the pipe is fully inserted past the olive and the nut is properly tightened to compress the olive against the pipe wall.
Pros and Cons
Pros
- No soldering or open flames required for installation
- Constructed from durable, corrosion-resistant brass
- Easy to disassemble for maintenance or pipe adjustments
- Compatible with a wide range of standard plumbing infrastructure
Cons
- Requires careful tightening to ensure the olive compresses evenly
- Not intended for use with non-standard pipe diameters
- Brass fittings may require thread tape for optimal leak prevention on the male thread
Setup, Compatibility & Care
To install, ensure the 15mm copper pipe is clean and free of debris. Slide the compression nut and olive onto the pipe, insert the pipe fully into the fitting body, and hand-tighten the nut. Follow up with a wrench to achieve the final seal; usually, a quarter-to-half turn past hand-tight is sufficient. Avoid over-tightening, as this can deform the olive or damage the brass threads. For the 3/4" BSP connection, apply PTFE tape to the male threads to ensure a drip-free connection. Periodically check fittings for signs of moisture or weeping after the system has been pressurized for 24 hours.
