The PU recoil hose for air tools from Tongxin is a spring tube in the company range of pneumatic tubing. A spring tube is a coiled air hose that stretches when a tool is in use and retracts when it is not, so the line stays off the floor and out of the way. The product page lists the spring tube series alongside PU, PE, EVA, paint, PU antifreeze, PU sand wrapped, PA nylon and nylon modified tubes, as well as dust blowing guns, quick couplings and plastic pneumatic fittings. The page describes the company as a producer and seller of these products with reliable quality and a favorable price.

What the Spring Tube Does

An air tool needs a hose that can reach the work without becoming a trip hazard. A coiled spring tube solves that by keeping the slack in a compact spiral. When the operator pulls the tool, the coil extends; when the tool is released, the coil pulls back. That is useful in a workshop with several benches, in a repair bay or on a production line where the hose would otherwise lie across the floor. The page does not give the working length, the retracted length or the coil diameter, so the buyer should confirm those values for the actual bench layout.

The spring tube is also a wear part. The coil flexes every time it is pulled, and the fittings at each end take the load. The buyer should check the tube material, the wall thickness and the fitting type, and should ask for the burst pressure and the working pressure. The page does not give those values, so they should come from the specification sheet. A tube that is too stiff will not retract well, while a tube that is too soft can kink and cut the airflow. A sample on the actual tool is the best way to judge the feel.

Coil, Fittings and Air Flow

The page lists a wide range of pneumatic connections, including quick plugs, self-locking connectors, ordinary pneumatic joints and plastic pneumatic fittings. That range matters because a spring tube is only useful if it connects to the tool and the air line without an adapter that leaks. The buyer should confirm the thread size, the coupling type and the hose inner diameter. The page does not give a flow curve, so the pressure drop should be checked on the actual tool. A small inner diameter can starve a high-consumption tool even when the compressor is adequate.

The coil itself should be matched to the tool weight. A heavy tool can stretch a light coil beyond its elastic range, while a heavy coil can pull on a small tool and tire the operator. The buyer should ask for the recommended tool weight and the number of coils. The page does not give those values, so a sample should be tested. For a bench with several tools, a shorter coil may be better than a long one, because the excess length is what makes a hose tangle.

Selection and Maintenance

The buyer should start with the tool, the air pressure and the distance to the outlet. The hose inner diameter, the working pressure and the fitting type follow from those inputs. The page does not give a pressure rating for the spring tube, so the buyer should confirm it before the order. A tube that is rated below the line pressure is a safety risk, not just a performance problem. The buyer should also check the tube against the air quality, because oil and water can affect some plastics.

Maintenance is simple but important. The coil should be inspected for cracks, kinks and worn fittings, and the fittings should be checked for leaks. A damaged coil should be replaced rather than taped or shortened, because a repair can create a weak point. The page does not give a service life, so the inspection interval should be set from the actual use.

Company and Ordering

Taizhou Luqiao Tongxin Pneumatic Tools Factory is listed with contact names Xueli Pan at 15857647888 and Zhengfu Chen at 13857647888, and an email address at txnj8@163.com. The company presents a product range that covers PU, PE, EVA, paint, antifreeze, sand wrapped and nylon tubes, dust blowing guns, quick couplings and pneumatic fittings. The page describes the products as reliable in quality and favorable in price.

A buyer who needs a quotation should send the tool type, the working pressure, the required length, the fitting type, the quantity and the destination. It is also useful to ask for the tube material, the inner and outer diameter, the burst pressure and the color options. The page does not publish a price or a delivery time, so those points should be confirmed in the quotation. A sample with the actual fittings is the best way to check the coil, the retraction and the airflow before a bulk order.

If you need a PU recoil hose for air tools or another spring tube for a workshop air line, send us the tool, the pressure, the length and the fitting type. We will confirm the spring tube specification, the fittings and the delivery plan, and we will point out the pressure and fit points that should be checked before the order is placed.
