Pneumatic Tubing Pipe 5/16" OD Blue PU Air Compressor Line: Is It Right for Your Shop?

A 39-foot blue polyurethane air line for pneumatic tools and more. Here's a close look at the listed specs, price, and trade-offs before you buy.

Last updated Aug 17, 2026

Choosing the right hose for your air compressor or fluid-transfer setup comes down to fit, flexibility, and the length you actually need. The Pneumatic Tubing Pipe 5/16" OD Blue Air Compressor PU Line is a polyurethane tube that aims to cover a lot of ground: pneumatic tools, instruments, mechanical gas pipelines, lab automation equipment, garden watering, and wine brewing. Here is a focused look at what the listing tells you before you add it to your cart.

Quick verdict

If you want a single 39-foot polyurethane line that can run from a compressor to a tool, or route through a lab and workshop, the blue PU line at USD 20.95 is a practical candidate. The 5/16" outside diameter is a clearly listed dimension, and the PU material is described as clear, resilient, and crack-resistant.

Who it suits

This line makes sense if you are setting up pneumatic tools, assembling lab automation equipment, or running small mechanical gas pipelines. The description also points to general industrial water, gardening, and wine brewing, so it is not limited to air-only duty.

What stands out from the listed details

The product is listed as a polyurethane (PU) tube with a 5/16" OD and a nominal wall thickness of 0.125 inches. The blue color helps you spot the line among other hoses. The 39-foot length gives you plenty of material for a single long run or several shorter sections. The description emphasizes a PU particle material that is not prone to yellowing, resists cracking, and has high resilience.

Meaningful trade-offs

Before choosing, consider that the 39-foot length is fixed. That is great for a long run, but if you only need a few feet, you'll have extra material to store or cut. The 5/16" OD is a specific size, so any push-to-connect fittings or ports need to be sized for that outside diameter. The listing describes four colors and eight sizes, which means you may find color or size options that suit your setup better if this specific blue roll isn't the perfect fit.
