Description
Overview:
The SIP 1/4" BSPT Equal Union Adaptor (MPN 04090) is a straight-through connector for joining two threaded lines of the same size, commonly used in compressed air, water, and general fluid transfer systems. Made from zinc-plated steel, it offers good corrosion resistance for workshop, site, and plant environments. Nitrile (NBR) sealing supports reliable, leak-resistant performance with air and many oils. With 1/4" BSPT threads on both ends (approximately 6.35 mm nominal size), this adaptor suits a wide range of tools and machinery with standard British pipe threads, including compressors, pneumatic tools, regulators, and manifolds. A high flow rate capability of 1000 litres per minute helps minimise restriction in high-demand setups, while the compact, lightweight form makes it easy to fit in confined spaces.
Key Features:
- Equal union with 1/4" BSPT threads on both ends (approx. 6.35 mm) for straightforward, like-for-like connections
- Zinc-plated steel body for durability and corrosion resistance in tough environments
- Nitrile sealing for dependable, leak-resistant joints in air and many oil-based applications
- High flow rate of 1000 litres per minute to reduce pressure drop in the line
- Straight-through bore for efficient flow and consistent tool performance
- Easy to install; use appropriate PTFE tape or thread sealant on BSPT taper threads where required
- Interchangeable with many leading-brand BSPT fittings of the same size
- Compact, lightweight component; simple to route and support on machinery and pipe runs
- Suitable for both industrial and residential workshop use
- Robust construction supports frequent connection and maintenance tasks
Typical Applications:
Connecting two 1/4" BSPT threaded lines in compressed air systems, workshop airlines, manifolds, pneumatic tools, spray equipment, coolant and lubrication lines, and general plumbing for non-potable water. Useful in maintenance, repair, and installation tasks on plant, garage equipment, and light industrial machinery where a reliable, straight union is needed.
