What kinds of polyethylene tubing do you manufacture?

Brotec manufactures low, medium and high density polyethylene tubing for a number of industries. The low density polyethylene tubing is ideal for irrigation, low pressure pneumatics, water sampling, chemical lines, beverage conveyance and for food contact applications. The medium density polyethylene tubing is an ideal compromise between the hardness of High Density and the flexibility of Low Density. The high density polyethylene tubing is used for fixed pneumatic installations or food and beverage networks.

Can you supply plastic tubing?

Brotec manufacture and supply tubing in various plastics materials. Nylon is commonly used for air tools and air supply around factories and low density polyethylene and polypropylene, which have a lower burst pressure rating than nylon, are often found in areas where food grade approved products are required.

Can you manufacture tubing in longer lengths than the standard 100 metres?

Brotec can manufacture longer lengths of tubing to your specifications but the lengths obtainable are dependent on the O.D. size of the tubing and the weight. Brotec uses sturdy white corrugated polypropylene packaging reels that are ideal for use in the field as they will not fall apart when wet, as happens with cardboard reels. Brotec polypropylene reels are recyclable. Brotec can also supply wooden reels that are custom made for more “heavy duty” applications.

What is the difference between Brotec Nylon11 and Nylon12?

The differences between Nylon11 and Nylon12 are relatively minimal especially when the product is used in a pneumatic application. Nylon11 is compounded from castor oil and the Nylon12 is compounded from oil. Their chemical resistance, moisture absorption, specific weight, hardness and elongation at break are the same. Nylon11 however, does perform at temperatures higher and lower than Nylon12.

I need a self-store hose to stretch over 15 metres. Which one do I get?

Brotec self-store hose is manufactured in 3 lengths. They are 7.5 metres, 15 metres and 30 metres. These lengths relate to the linear amount of tubing in the coil. To ascertain the working length you need to divide the linear length by 2. Brotec recommend that you only stretch the coil out to 50% of its linear length. Therefore a 7.5 metre coil will have a working length of 3-4 metres, a 15 metre coil will have a working length of 7.5 metres and a 30 metre coil will have a working length of 15 metres. If the coils are continually extended beyond their specified working length they lose their ability to retract.

I’m not sure if I should use low density polyethylene or nylon for my pneumatic lines?

Brotec nylon and polyethylene are both suitable for use in pneumatic systems. You need to consider the burst pressures that you require and the working conditions of the tubing. Nylon has a burst pressure of 1000psi and polyethylene tubing has a burst pressure of 600psi. However, whilst Nylon operates at between -20degC and 120degC, the polyethylene will perform up to 65degC but with a much reduced burst pressure.

I’m looking for D.O.T. air brake tubing. What does this mean?

Brotec air brake tubing is manufactured to several standards such as the European DIN74324 and the American standards J844 Type A and J1394 Type A. When D.O.T. is specified it relates to the American standards. The fittings are also specified D.O.T. which stands for the American Department of Transport. Brotec air brake tubing is manufactured to D.O.T. specifications.
