Red 27mm (3/4″) ABS Aspirating Pipe 90 Degree Bend
£1.56 (inc VAT: £1.87)
Summary
The Plimat REDCUP0250 is a plain red ABS 90 degree bend designed specifically for 27mm (3/4″) 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 REDCUP0250 provides a reliable solution for changing pipe direction in aspirating smoke detection systems. The 90 degree sweeping bend configuration allows for efficient routing of sampling pipe networks whilst minimising air loss and maintaining system performance. Manufactured under strict BS EN ISO 9001 quality control procedures, this fitting is tested and approved to EN 54-20 standards, ensuring full compliance with UK and European fire safety regulations for aspirating smoke detection systems.
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 homogenous 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 sweeping bend in aspirating pipe networks?
The 90 degree sweeping 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 through its gradual radius, which is critical for maintaining system performance and sensitivity in aspirating smoke detection applications.
Which aspirating smoke detection systems is the REDCUP0250 compatible with?
The REDCUP0250 is compatible with all major brands of low-pressure aspirating smoke detection systems including VESDA, FAAST, ICAM and other leading ASD manufacturers. The fitting is approved to EN 54-20 standards required for these systems and is specifically designed for 27mm (3/4″) aspirating pipe networks.
What is the difference between 25mm and 27mm aspirating pipe?
The 27mm (3/4″) pipe has a larger internal diameter compared to 25mm pipe, allowing for higher airflow capacity and longer pipe runs in aspirating smoke detection systems. The choice between 25mm and 27mm depends on the system design, area coverage requirements and pipe network calculations provided by the ASD system manufacturer or certified distributor.
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 using approved plastic pipe cutters, ensuring cutters are sharp, removing all burrs, abrading both the pipe ends and the fitting interior, cleaning surfaces, then applying the correct ABS solvent cement (such as Plusbond 3019) before pushing the components together. The joint must be held steady whilst the solvent sets and allowed to cure fully before testing. Pipe clips should be installed every 800mm along the length of pipe.
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 are the chemical resistance properties?
The ABS material provides excellent chemical resistance to a wide range of acids, alkalis and aggressive chemicals. The homogenous material construction ensures consistent chemical resistance throughout the fitting, making it suitable for installation in industrial environments, chemical processing facilities, laboratories and other areas where corrosive substances may be present.
Can the bend be installed outdoors or in direct sunlight?
Whilst the ABS material is suitable for outdoor applications and maintains its properties across the full temperature range from -40°C to +70°C, it should not be installed in direct continuous sunlight. Prolonged UV exposure can affect the material properties over time. For outdoor installations, the pipework should be protected from direct sunlight or alternative UV-resistant materials should be considered.
What standards does the REDCUP0250 comply with?
The bend is manufactured under a BS EN ISO 9001 quality control system and is approved to EN 54-20 (fire detection and fire alarm systems – aspirating smoke detectors), ensuring full compliance with UK and European fire safety regulations for aspirating smoke detection systems.
