Product Information
Full details
The Primaplumb 40mm 90° Knuckle Bends are an essential plumbing fitting designed for homeowners and professional tradespeople looking to achieve precise pipe routing in confined spaces. These bends allow for smooth 90-degree turns without requiring pipe cutting or heat-bending, ensuring a secure and leak-free connection in various drainage applications. While these fittings are highly effective for redirecting flow in tight areas, it is important to ensure they are used exclusively with compatible 40mm pipe systems to maintain a watertight seal.

FAQs
Are these bends compatible with all 40mm pipe?
Yes, they are designed to fit standard 40mm waste pipe sizes used in most plumbing installations.
Can I use these for high-pressure water lines?
No, these are strictly intended for gravity-fed drainage and waste plumbing systems.
Do I need glue to install these?
Depending on your specific pipe system, these are often push-fit, but always follow the manufacturer's guidance for your specific pipe type.
Can these be used outdoors?
While durable, they are primarily designed for internal residential and trade plumbing applications.
What is the angle of these bends?
These specific fittings are designed for a 90-degree turn.
Troubleshooting
The connection is leaking
Check that the pipe is fully inserted past the O-ring and that the pipe end is not cracked or deformed.
Pipe is difficult to insert
Ensure the pipe is 40mm diameter and apply a small amount of silicone lubricant to the pipe end to help it slide past the seal.

Setup, Compatibility & Care
To install these bends, first ensure your 40mm pipe ends are cut square and are free from debris or burrs that could compromise the seal. Simply push the pipe into the knuckle bend until it reaches the internal stop. If using push-fit style connections, ensure the integrated 'O' ring is properly seated. For optimal care, avoid using abrasive chemical cleaners on the exterior, and occasionally inspect the connection points under sinks for any signs of moisture to ensure the integrity of the plumbing system remains intact.
