Red 25mm ABS Aspirating Pipe 90 Degree Bend
£1.56 (inc VAT: £1.87)
Summary
The Plimat REDCUI0250 is a plain red ABS 90 degree bend designed specifically for aspirating smoke detection pipe networks. This essential fitting enables installers to divert pipework around obstructions whilst maintaining optimal airflow characteristics through its sweeping radius design. The bend is manufactured from high-quality Acrylonitrile Butadiene Styrene (ABS) and features the distinctive red colour that immediately identifies components as part of a fire safety system.
Engineered for professional installation in demanding environments, the REDCUI0250 provides a reliable solution for changing pipe direction in aspirating smoke detection systems. The 90 degree configuration allows for efficient routing of sampling pipe networks whilst the sweeping bend design minimises air loss and maintains system performance. Manufactured under strict BS EN ISO 9001 quality control procedures, this fitting is tested and certified to EN 54-20 and EN 61386-1 standards, ensuring full compliance with UK and European fire safety regulations.
The bend’s robust ABS construction delivers exceptional durability across a wide temperature range from -40°C to +70°C, making it suitable for installation in cold stores, industrial facilities, data centres and outdoor applications. The material exhibits excellent chemical resistance to acids, alkalis and aggressive chemicals, whilst maintaining high impact strength and toughness throughout its service life. Installation is straightforward using standard ABS solvent cement welding techniques, creating permanent, leak-free connections that exceed the strength of the pipe itself.

FAQ
What is the purpose of a 90 degree bend in aspirating pipe networks?
The 90 degree bend allows installers to change the direction of aspirating pipe networks to route around obstacles such as structural elements, services and equipment. The sweeping bend design maintains optimal airflow characteristics by minimising turbulence and air loss, which is critical for system performance and sensitivity.
Which aspirating smoke detection systems is the REDCUI0250 compatible with?
The REDCUI0250 is compatible with all major brands of low-pressure aspirating smoke detection systems including VESDA, FAAST, ICAM and other leading ASD manufacturers. The fitting meets industry standards required for these systems and is specifically designed for aspirating pipe networks.
What temperature range can the bend operate in?
The ABS material performs reliably across temperatures from -40°C to +70°C, making it suitable for demanding environments including cold stores, freezer rooms, industrial facilities, data centres and outdoor applications. The material maintains its impact strength and toughness throughout this entire temperature range.
How is the bend installed?
Installation involves cutting pipe ends squarely, removing all burrs, abrading both the pipe ends and the fitting interior, cleaning with MEK cleaner, then applying ABS solvent cement before pushing the components together. The joint must be held steady for 30 seconds and allowed to cure before testing. Full cure times vary depending on temperature and humidity but typically require 24 hours before pressure testing.
Why is the bend red in colour?
Red is the standard colour for aspirating smoke detection pipes and fittings, serving to instantly identify the components as part of a fire detection system. This visual identification helps prevent accidental damage or interference during building maintenance and clearly distinguishes fire system pipework from other building services.
What standards does the REDCUI0250 comply with?
The bend is manufactured under a BS EN ISO 9001 quality control system and is tested and certified to EN 54-20 (fire detection and fire alarm systems – aspirating smoke detectors) and EN 61386-1 standards, ensuring full compliance with UK and European fire safety regulations.
What are the chemical resistance properties?
The ABS material provides excellent chemical resistance to a wide range of acids, alkalis and aggressive chemicals. This makes the fitting suitable for installation in industrial environments, chemical processing facilities, laboratories and other areas where corrosive substances may be present.
Can the bend be used outdoors?
Yes, the ABS material is suitable for outdoor applications and maintains its properties across the full temperature range from -40°C to +70°C. However, care should be taken to protect the pipework from direct continuous sunlight exposure which may affect the material over extended periods.
