British special metal companies Cole Tubes - that have roots back to 1807 - and Swallow Metals & Components - metal and ceramic components & assemblies suppliers - merged at the end of March 2005 as Cole & Swallow Materials Limited. So their product range has been significantly extended. On its precision tube side they work to tolerances which can only be achieved by cold drawing and offer a range of finishing operations too. Acting as mill agents  Cole & Swallow hold stocks of a large range of special & precision products for a variety of end uses: nickel alloy & stainless tube, special brass machining rods, pneumatic cylinder tubes, control panel switch components and much more. If we don't have stock we can usually offer a quick delivery on even very hard to find materials. An uncommon expertise that you can reach from R&W near you.

Pneumatic Tubes
Cole & Swallow Metals specialise in tubes for use in the manufacture of pneumatic cylinders. Produced and manufactured from quality aluminium alloys in Switzerland to internationally recognised standards for the pneumatics industry. Cole Tubes offer the complete range of standard sizes and can also meet your requirements for bespoke sizes. For more information about your requirements or unusual product specifications, please contact R&W.

Many of Cole & Swallow customers prefer to order their pneumatic tubes complete and ready to install, rather than in component or semi-finished condition. However, they can deliver your order manufactured to whatever level of completion that is required.

Aluminium pneumatic cylinder tubing is supplied in alloy 6063 T6, porthole extruded to H11 tolerances on the inside diameter. It is anodised inside and outside to a minimum thickness of 20 µm. It can be supplied in lengths of 3000mm to 3500mm. Please note that the 160mm diameter and 200mm diameter tubes are seamless extruded and drawn.
Custom extrusion of profiles other than circular are all available either from stock or by custom manufacture to special order.

Precision Tubing
Tube Manipulation
Cole tubes produce fabricated tubular parts for instrumentation, pressure gauges. sensing probes, antennas and components for associated industries. operations include swaging, flaring, coiling and brazed assemblies. Fininshing operations are also available and include electroplating and chemical blackening.
Thin Wall Tube
Available in Mill quantities or from stock. As with other products, deliveries can be scheduled over an agreed time period if required. Tube is supplied in cut or random straight lengths. outside diameters are produced between 0.2 and 60mm, depeneding on metal or alloy. Wall thickness range from 0.04mm, depending on diameter.
Refractory tubes
For use at high temperatures or in corrosive atmospheres, refactory metal tubes made from molybdenum, tungsten, tantalum, rhenium and their alloys are available.
Capillary Tubing
Available on plastic spools, in coils, in straight and precision cut lengths. Uses include hypodermic needles, micro containers and fibre optics. A wide range of sizes in stainless steel, copper alloys and mild steel is available.

Precision Tubes are available in the following materials
Aluminium, Anticorodal 100 (ALMgSi 1), Beryllium Copper CuBe2, Brass (leaded & unleaded), Carbon Steel, Constantan 45, Copper (DHP, OFLP, OFHC), Cupro Nickel (90/10,80/20), Gold, Hasterlloy+, Inconel (600, X-750)*, Kover* , Lead, Molybdenum, Monel (400, k500)*, Nickel, Nickel Chrome (80/20), Nickel Iron (36, 48 and 52 alloys), Nickel silver (CuNi12Zn24 and CuNi 18Zn30), Niobium, Niobium 1% Zirconium, Ni-Span C 902*, Palladium, Peraluman 150 (A1 Mg 1.5), Peraluman 300 (A1 Mg 3), Platinum, Rhenium Molybdenum, Silver, Stainless Steel (AISI 304, 304L, 316L, 316Ti, 321),
Stainless Steel (410, 430, 446), Tantalum, Titanium, Tungsten
Bimetallic Tubes
When complex working environments mean that copper alloys on their own cannot provide a heat exchange solution it may be possible to use a bimetallic tubing. Combined tubes can be produced with copper alloy, aluminium, titanium, carbon or stainless steel combinations. Bimetallic tubing gives combined properties of heat exchange, strength and corrosion resistance that single tubes cannot provide. Ferrules can be fitted to ensure the "wetted" ends are all of one material type.
