Air Line SpeedFit Systems

About Air Line SpeedFit Systems

Air Line SpeedFit Systems represent a modern, efficient solution for creating and maintaining compressed air distribution networks in workshops, garages, and industrial settings. These innovative push-fit systems eliminate the need for traditional threaded connections, soldering, or specialist tools, allowing tradespeople to install or modify air line configurations quickly and reliably. The range includes various adaptors, couplings, elbows, tees, reducers, and aluminium piping that work seamlessly with popular SpeedFit brands including John Guest, SharkBite, and CAS Fast Fit systems.

At TooledUp.com, our Air Line SpeedFit Systems collection features an extensive selection of Sealey components designed to create professional-grade compressed air networks. Whether you're establishing a new workshop air supply, extending an existing system, or replacing worn fittings, these push-fit components offer exceptional versatility. The systems accommodate various pipe sizes and BSP thread standards commonly used throughout UK workshops, with brass wingback elbows, stem adaptors, and straight adaptors providing secure connections that can be reconfigured without cutting or wasting materials.

The beauty of SpeedFit technology lies in its simplicity and reliability. Components feature secure grip rings and O-ring seals that create leak-free connections capable of handling typical workshop air pressures. This makes them ideal for connecting air tools, tyre inflators, spray guns, and other pneumatic equipment. With assortments available containing up to 32 pieces, you can keep essential fittings on hand for quick repairs or system modifications, minimising downtime in busy professional environments.

Jargon Buster

• BSP (British Standard Pipe): The UK threading standard for pipe fittings, measured in inches (e.g., 1/2" or 3/4"). Parallel BSP threads (BSPP) are commonly used in compressed air systems and require a sealing washer for leak-free connections.
• Wingback Elbow: A push-fit elbow fitting with protruding "wings" that allow for easy hand-tightening and removal without tools. Brass wingback elbows provide durable, corrosion-resistant connections for changing direction in air line systems.
• Stem Adaptor: A fitting that converts between SpeedFit push-fit connections and traditional BSP threaded connections, allowing integration with existing air tools, compressors, and equipment.
• Reducer/Reducing Tee: A fitting that connects pipes of different diameters, such as 22mm to 15mm, allowing you to branch off smaller air lines from main distribution pipes without compromising flow in the primary line.
• Anodised Aluminium Pipe: Lightweight, corrosion-resistant piping with a protective anodised coating that extends service life. Aluminium pipe is significantly lighter than steel alternatives, making installation easier whilst maintaining strength and durability.
• Pneumatic Coupling: Quick-release connectors that allow rapid connection and disconnection of air tools without air loss. Essential for workshops where multiple tools share a single air supply.

How to Choose the Right Air Line SpeedFit Systems

Identify Your System Compatibility: Determine which SpeedFit system you're working with—John Guest, SharkBite, or CAS Fast Fit. Whilst these systems share similar push-fit principles, specific components are designed for each brand. Check existing fittings to ensure compatibility, or consider standardising on one system for your entire workshop.

Assess Required Pipe Sizes: Most workshop air systems use 15mm or 22mm pipe, with 15mm suitable for shorter runs and lighter-duty applications, whilst 22mm provides better flow rates for longer distances or high-demand tools. Consider using reducers to branch smaller lines from main distribution pipes, maintaining pressure where it's needed most.

Plan Your Thread Connections: Identify the BSP thread sizes on your compressor, air receiver, and tools. Common UK standards are 1/4", 3/8", 1/2", and 3/4" BSP. Select appropriate stem adaptors and wingback elbows to connect SpeedFit piping to these threaded components.

Calculate Configuration Requirements: Sketch your air line layout noting where you need straight runs, direction changes (elbows), branches (tees), and connection points. The 30-piece or 32-piece assortments provide excellent value if you're establishing a new system or maintaining multiple locations, ensuring commonly needed fittings are always available.

Consider Future Expansion: SpeedFit systems excel at modification and expansion. Installing ball valves at strategic points allows you to isolate sections for maintenance or add new branches without depressurising the entire system. End plugs enable you to cap off potential future connection points during initial installation.

Material Selection: Brass fittings offer superior durability and corrosion resistance compared to plastic alternatives, making them ideal for professional environments. Anodised aluminium piping provides an excellent balance of strength, weight, and longevity for permanent installations.

Safety Information

Compressed air systems require proper installation and maintenance to ensure safe operation. Always depressurise air lines completely before disconnecting or modifying SpeedFit fittings. Ensure all connections are fully inserted and secure before pressurising—partially connected fittings can blow off under pressure, causing injury. Never exceed the maximum working pressure specified for your components, typically 10-15 bar for workshop systems.

Regularly inspect fittings, particularly O-ring seals, for wear, damage, or deterioration. Replace any components showing signs of degradation before they fail. When working with compressed air, wear appropriate PPE including safety glasses, as debris can be propelled at high velocity. Avoid directing compressed air towards yourself or others—serious injury can result from air injection under the skin.

Follow HSE guidelines for compressed air systems, ensuring adequate pressure relief valves are fitted to prevent over-pressurisation. Install moisture separators and filters to prevent water accumulation, which can cause corrosion and compromises system integrity. Never use compressed air to clean clothing whilst wearing it, and ensure proper ventilation when using air-powered spray equipment.

Frequently Asked Questions

Can I mix different SpeedFit brands in the same system?
Whilst the principle is similar, John Guest, SharkBite, and CAS systems use slightly different specifications. It's recommended to use components designed for your specific system to ensure proper sealing and reliability. If you need to connect different systems, use appropriate transition adaptors.

What's the maximum pressure rating for SpeedFit air line systems?
Most SpeedFit components are rated for 10-15 bar working pressure, which comfortably accommodates typical workshop compressor outputs of 8-10 bar. Always check individual component specifications and never exceed stated maximums. Remember that pressure ratings may decrease with temperature or when using worn components.

How do I disconnect SpeedFit fittings without damaging them?
First, fully depressurise the system. Push the collet (the outer ring) towards the fitting body whilst gently pulling the pipe outward. If fittings are stubborn, specialist release tools are available. Never use excessive force or sharp implements that might damage the O-ring seals or grab ring.

Do I need to use any sealant with SpeedFit push-fit connections?
No—the push-fit connections rely on internal O-rings for sealing and don't require PTFE tape or sealant. However, when connecting to BSP threaded components like compressors or tools, you should use PTFE tape on the male threads to ensure leak-free connections.

Can SpeedFit systems be used outdoors or in unheated workshops?
Yes, brass and anodised aluminium components are corrosion-resistant and suitable for outdoor use. However, protect systems from freezing conditions, as trapped moisture can freeze and crack fittings or pipes. Install the system with a slight fall towards drain points and fit automatic drain valves to remove condensation regularly.
