FAQs
What type of joint does this fitting use?
This is a solvent weld fitting, designed to be joined using appropriate ABS solvent cement for a permanent, secure connection.
What is the maximum continuous temperature this bend can handle?
It is suitable for a constant temperature of 60°C. Intermittent discharges up to 90°C are acceptable.
Can I use this with PVC pipes?
No, this fitting is made of ABS and is designed for use with ABS pipes and fittings using ABS solvent cement. Using it with other materials may result in a poor or failed joint.
What does Kitemarked to BS EN 1455-1:2000 mean?
This certification indicates that the product has been tested and meets the British and European standards for plastic piping systems for soil and drain, including waste water, applications outside buildings.
How do I ensure a strong joint?
Proper preparation is key: ensure surfaces are clean, dry, and free from grease. Apply the correct solvent cement evenly to both surfaces and hold the joint for the recommended time after assembly to allow it to set.
What sizes are available?
The OsmaWeld range of fittings, including this knuckle bend, is available in 32/40mm and 50mm diameters.
Troubleshooting
Joint leaks after installation
Ensure pipes were clean and dry before solvent welding, sufficient solvent cement was used, and the joint was held securely during the initial set time. Re-joint if necessary.
Difficulty pushing pipe into socket
Check for any obstructions or debris inside the socket or on the pipe end. Ensure you are using the correct diameter fitting for your pipe.
Discoloration of fitting
This may occur with prolonged exposure to sunlight or certain chemicals. While generally cosmetic, ensure it does not affect the structural integrity. Avoid flushing with harsh solvents.
Pros and Cons
Pros

- Quick and straightforward installation due to push-fit design.
- ABS material ensures durability and resistance to common waste materials.
- Designed to handle varying temperatures common in drainage applications.
- Meets industry standards, offering peace of mind.
- Compact 90-degree angle aids in navigating tight spaces.
Cons
- Continuous use at temperatures above 60°C is not recommended.
- Requires appropriate solvent cement for a secure connection.
- Color options might be limited depending on the specific product variant.
- Primarily designed for waste systems, not high-pressure applications.
Setup, Compatibility & Care
Setup: Ensure pipes are clean and dry before applying solvent cement. Apply solvent cement evenly to both the pipe end and the inside of the socket. Push the pipe into the socket with a slight twisting motion until it bottoms out. Hold firmly for 30 seconds to prevent push-out. Allow adequate drying time as per the solvent cement manufacturer's instructions before testing.
Compatibility: This 40mm OsmaWeld knuckle bend is designed to connect with other 40mm OsmaWeld fittings and pipes. It is suitable for use in ABS solvent weld waste systems. Always ensure the diameter matches the pipe being connected.
Care: The OsmaWeld system requires minimal ongoing care. Periodically check for any signs of leakage at joints. Avoid flushing the system with highly aggressive solvents or chemicals that are not part of normal household waste, as these could potentially degrade the ABS material over time.
