Choosing pneumatic tubing for refrigeration lines means balancing reach, diameter, material, and working pressure. The Robertshaw 11-193 offers a 50-foot length in a 1/4-inch outside diameter, with aluminum construction and a 90 psi working pressure rating-all for USD 31.69. This guide looks at what that combination means for a single product decision.
Quick Verdict
If you need one continuous 50-foot run of 1/4-inch aluminum tubing for a refrigeration pneumatic system, the Robertshaw 11-193 is a straightforward pick. The 90 psi working pressure rating is clearly stated, and the aluminum material is specified in the product name. At USD 31.69, the price covers the stated length and size.
Who It Suits
This tubing suits a shopper who wants a 50-foot coil of 1/4-inch aluminum line for refrigeration-related pneumatic tubing setups. Because the working pressure is listed at 90 psi, it fits systems designed for that pressure range. If you need a longer or shorter run, or a different diameter, this particular listing specifies only the 50-foot, 1/4-inch option, so you would weigh that against your project needs.
What Stands Out From the Listed Details
The most useful details are the ones you see right in the title: aluminum material, 50-foot length, and 1/4-inch outside diameter. The description adds a 90 psi working pressure rating, which is a concrete number for planning. The product is listed as new, with a country of origin of the US.
Meaningful Trade-Offs
The working pressure is 90 psi. That is the only pressure figure supplied, so you should confirm your system's operating pressure stays within that limit. Aluminum is not a flexible material; if your installation requires tight bends or repeated maneuvering, you may need to plan support and bend radius accordingly. The price is USD 31.69, which reflects one coil of this size and material.
Bottom Line
The Robertshaw 11-193 is a focused option for a specific need: 50 feet of 1/4-inch aluminum pneumatic tubing with a 90 psi working pressure. It doesn't try to be a universal hose; it is a single, clearly specified refrigeration tubing product. If those specs match your job, the listed price of USD 31.69 gives you the exact length and material without extra features you might not use.
