Product Information
Full details
The Primaplumb 32mm 90° Knuckle Bends are designed for professional plumbers and DIY enthusiasts alike who need to navigate tight spaces in drainage and waste pipe systems. These fittings provide a reliable, leak-proof solution for redirecting 32mm pipe runs without requiring complex cutting or manual pipe bending. While they offer excellent convenience, they are specifically engineered for 32mm pipe diameters, meaning they will not fit standard 40mm or other pipe sizes, requiring careful measurement before purchase.

FAQs
Can these be used on 40mm pipes?
No, these are strictly designed for 32mm piping and will not provide a secure fit for 40mm pipework.
Do I need solvent weld glue for these?
No, the Primaplumb 32mm Knuckle Bends are push-fit and rely on integrated seals rather than chemical welding.
Are these suitable for hot water discharge?
They are designed for standard domestic waste and drainage; check your local plumbing codes regarding temperature ratings for waste pipes.
Can I remove and reuse the fitting?
While the push-fit design is secure, it is intended for semi-permanent installation. Reuse may be possible, but always inspect the integrity of the internal seal first.
Do I need to lubricate the pipe before insertion?
While usually unnecessary, a tiny amount of silicone-based plumber's lubricant can make insertion easier if the pipe fit is particularly tight.
Troubleshooting
Pipe will not insert fully into the fitting
Check that the pipe is cut perfectly square and remove any rough edges or burrs with a file.
Joint is weeping or leaking
Disconnect the joint and inspect the internal rubber seal for debris or damage. Ensure the pipe is inserted fully past the seal.
Pros and Cons
Pros
- Tool-free push-fit installation
- Space-saving compact design
- Eliminates the need for pipe cutting
- Robust leak-proof seal
Cons
- Limited to 32mm pipe diameter only
- Not suitable for high-pressure supply lines

Setup, Compatibility & Care
To install, ensure the 32mm pipe end is cut square and deburred to prevent damage to the internal seals. Simply push the pipe firmly into the knuckle bend until you feel it seat against the internal stop. No specialized plumbing tools or glues are required for standard assembly. For maintenance, periodically check the joints for moisture. If a joint needs to be repositioned, ensure the seals remain free of debris before re-inserting the pipe. Always verify your pipe diameter with a caliper before installation to ensure a tight, permanent fit.
