Aluminium

Aluminium hose fittings and pipe adaptors for pneumatic, compressed air and industrial fluid transfer. Aluminium is lighter than brass or steel and has good corrosion resistance in dry and low-moisture environments, making it a practical choice where weight matters: portable equipment, overhead pipework, or mobile plant machinery. The range covers hex nipples, reducing bushes, elbows and adaptors in BSP thread sizes.

Like brass fittings, aluminium uses BSP thread forms in both parallel (BSPP) and tapered (BSPT) variants. BSPP threads require a face seal or O-ring; BSPT threads seal on the taper with PTFE tape. One important check before ordering: aluminium is susceptible to galvanic corrosion when in direct contact with dissimilar metals in the presence of moisture. In mixed-metal systems, consider using an isolating connector or selecting fittings in a compatible material throughout.

Choosing aluminium hose fittings

Aluminium hose fittings occupy a specific niche in fluid and pneumatic systems: lighter than brass, stronger than plastic, and with enough corrosion resistance for most dry industrial environments. Where weight is a factor, portable compressor equipment, mobile plant, overhead air line runs, aluminium is worth specifying over brass.

The thread standard is the same as brass fittings: BSP in both parallel (BSPP) and tapered (BSPT) forms. BSPP threads seal with a face seal or bonded washer; BSPT threads seal on the taper with PTFE tape. The two are not interchangeable, so confirm which thread type your equipment uses before ordering.

Galvanic corrosion is worth considering when aluminium fittings are used alongside other metals. Aluminium is relatively active electrochemically, and when in direct contact with copper, brass or steel in a damp environment, preferential corrosion can occur at the contact point. In mixed-metal systems, either keep the full assembly in aluminium or use an appropriate isolating fitting.

For compressed air systems, aluminium is a reliable choice in clean, dry air environments. If the air contains significant moisture or condensate, common in poorly maintained systems, the internal surfaces can suffer from oxidation over time. A functioning air dryer or filter unit ahead of the line helps preserve fitting service life.

Frequently Asked Questions

What are aluminium hose fittings used for?

Aluminium hose fittings are used in pneumatic, compressed air and general industrial fluid systems where weight is a consideration. Common applications include portable air equipment, overhead air line installations, mobile plant and anywhere a lighter fitting is preferable to brass or steel without compromising on strength.

How do aluminium fittings compare to brass?

Aluminium is lighter than brass and has comparable corrosion resistance in dry environments. Brass has better resistance to moisture and is less susceptible to galvanic corrosion in mixed-metal systems. For most dry pneumatic applications, aluminium works well. In wet or damp environments where moisture is present, brass is generally the more reliable choice.

Are aluminium fittings compatible with BSP threads?

Yes. Aluminium fittings in this range use standard BSP threads in both parallel (BSPP) and tapered (BSPT) variants. They are dimensionally compatible with brass, steel and other materials using the same thread standard. Always confirm the thread type before ordering.

Can aluminium fittings be used outdoors?

Aluminium has reasonable resistance to atmospheric exposure but is not as robust as brass in wet or coastal environments. If fittings will be exposed to prolonged moisture, road salt or marine conditions, brass or stainless steel is the safer choice. For sheltered outdoor installations in dry conditions, aluminium is generally adequate.

Do aluminium pipe fittings corrode?

Aluminium can corrode in specific conditions. It is vulnerable to galvanic corrosion when in direct electrical contact with dissimilar metals such as copper or steel in a damp environment. It can also be attacked by strongly alkaline or acidic fluids. In clean, dry compressed air systems, aluminium corrosion is not normally a concern.
