Aluminium
Light, corrosion-resistant fittings for marine and structural pipework where weight matters.
- Aluminium 6061
- Aluminium 6063
- Aluminium 5083
- Aluminium 5086
Standards: ASTM B361, ASME B16.9
Pipe Fittings
Butt weld and forged fittings in aluminium, high nickel alloys, cupro-nickel and stainless steel.
Overview
Fittings matched to the line they join
We supply pipe fittings across four material families, so the fitting can be specified to match the pipe and the medium rather than the other way round. The range covers butt weld fittings — elbows, tees, reducers, caps, stub ends and crosses — as well as forged socket weld and threaded fittings.
Sizes, schedules and the applicable standard are confirmed against each enquiry.
