Acetal Tube 20mm to 250mm OD – Natural Acetal Copolymer (POM-C) Hollow Bar, 100mm to 3000mm Lengths

Natural acetal copolymer (POM-C) tube in 35 sizes, from 20mm to 250mm outside diameter. Acetal tube is a strong, highly machinable engineering plastic with excellent wear and impact resistance. It is supplied oversize to allow for machining and finishing to the stated size, which makes it the quick way to make bushes, bearings, rollers and seals without boring out solid rod.

Why choose acetal tube

• Excellent resistance to impact and wear
• Good mechanical strength and rigidity
• Highly machinable – supplied oversize for machining and finishing to size
• Not hygroscopic, so it suits uses where absorbing liquid is not wanted
• Good resistance to many acids, cleaning agents and solvents
• Excellent electrical insulation properties
• Working temperature from -50°C up to +100°C
• Suitable for marine environments

Size, length and weight guide

Sizes are outside diameter (OD) x inside diameter (ID). Wall thickness is (OD − ID) ÷ 2. Weights are approximate, per metre, worked out from a density of 1.41 g/cm³.

Which acetal or tube do I need?

• Acetal tube (this listing) – a ready-made bore for bushes, rollers and sleeves, with less machining and less waste than solid rod.
• Natural acetal rod – solid acetal copolymer bar when you need a solid part or a bore size not listed here.
• Delrin® acetal homopolymer rod – for parts that need extra strength, stiffness and creep resistance.
• PTFE tube – for higher temperatures and the widest chemical resistance.
• Clear polycarbonate tube – when you need to see through the tube.

FAQ

Q: What sizes is acetal tube available in?
A: 35 sizes from 20mm OD x 10mm ID up to 250mm OD x 220mm ID. See the size table above for every OD, ID and wall thickness.

Q: Is the tube exactly the stated size?
A: No. It is supplied oversize so it can be machined and finished to the stated size.

Q: Can I buy a short length?
A: Yes. Popular sizes from 30mm to 80mm OD come in 100mm, 250mm, 500mm, 1000mm, 2000mm and 3000mm lengths. For a length or size not listed, please get a quote.

Q: Can I return cut lengths?
A: Cut lengths are made to order and can't be returned. Please check your measurements before ordering.

Q: Is acetal tube OK in the cold?
A: Engineering plastics can become brittle in extreme cold, so it is best not to machine or store acetal tube in very cold conditions.
