ABS Fittings Inch

More Info

Georg Fischer GF ABS Inch Fittings are a comprehensive, high-performance range of fittings designed for solvent-cemented ABS (Acrylonitrile Butadiene Styrene) pipe systems in imperial (“inch”) sizes. These fittings are engineered for durability, reliability, and compatibility, making them ideal for a wide array of industrial, commercial, and building plumbing applications where strong, weather-resistant, chemical-resistant connections are required.

Key Features & Technical Specifications

Material: Manufactured from ABS, a halogen-free thermoplastic known for its excellent impact resistance, especially at low temperatures, and good resistance to many chemicals and weathering.
Sizes Available: Inch sizes—from 3/8″ up to 8″ for various fitting types.
Temperature Range: −40 °C up to +60 °C under standard operating conditions.
Pressure Ratings: Depending on size and class, pressure ratings are in the order of 6 to 25 bar at 20 °C. For many fittings in the Inch/Imperial line, typical working pressures are up to ~15 bar at 20 °C.
Standards / Dimensions:
- Fittings built to conform with ISO 727-2 and BS 5392 for imperial ABS fittings.
- Pipe dimensions also match BS 5391-1 for ABS pipe, ensuring that pipes and fittings are compatible, with tight tolerances.
Jointing Method: Solvent weld/cement jointing, which requires correct surface preparation and solvent cement (often provided or specified by GF) to form durable joints.

Applications & Suitability

Environmental & Usage Benefits:
- Good UV and weather resistance.
- Suitable for use in cold environments thanks to its impact toughness at low temperatures.
- Lightweight compared to many metal fittings, with lower maintenance and corrosion concerns.
Typical Applications: Potable water systems, pressure systems, food and beverage manufacture, water treatment, chemical processing, HVAC / chilled water, where impact resistance, chemical compatibility, and solvent weld joints are required.

Why Choose Georg Fischer?

When specifying or installing ABS pipework, the choice of fittings is crucial to the reliability and longevity of the system. Georg Fischer stands out from other brands for several reasons:

Unmatched Reputation – With over 200 years of engineering expertise, Georg Fischer is a globally trusted manufacturer. Their ABS systems are used in critical industries where failure is not an option.
Precision Manufacturing – GF fittings are produced to strict tolerances, ensuring consistent fit and reliable solvent-weld joints. This precision reduces the risk of leaks and installation issues compared with lower-grade alternatives.
Comprehensive Approvals – Unlike many generic ABS fittings, GF products carry recognised approvals such as WRAS, BS, and ISO compliance. These certifications provide assurance to specifiers, installers, and inspectors that the system is safe for potable water and compliant with UK regulations.
Superior Material Quality – Georg Fischer uses virgin ABS resin for strength, chemical resistance, and durability, while some cheaper brands may use recycled or mixed plastics that compromise performance.
System Compatibility – GF fittings are designed as part of a complete system with matching pipes, valves, and accessories. Choosing a single, proven brand ensures seamless compatibility and avoids the risks of mixing components from multiple manufacturers.
