Paddle Blinds in Isolation, Hydrotest & Custom Thicknesses
Also referred to as a paddle flange, paddle blank, line blank, isolation or test blind, flange skillet, and more.
A paddle blind is generally used as a temporary blocking device to stop flow in a process piping system that does not require constant maintenance.
With our in-house engineering team, we manufacture our paddle blinds on-site using precision CNC plasma and waterjet machines. With speed and precision to manufacture new and custom paddle blinds, as well as a huge inventory of rental paddle blinds in-stock and ready to ship 24/7-365 days of the year, we can have them where you need them, when you need them!

Frequently Asked Questions
We ARE the manufacturer and not a reseller. Since 1982 our blinds are not just "cut and shipped metal," we deliver them to you as a finished products. Every blind we manufacture is sent out with perfect symmetry, clean edges, fresh paint, marked or stamped and with color coded handles for quick identification of the flange rating from a distance.
In addition, though others might claim this, USA Industries has the largest stock available for immediate delivery along with immediate in-house production.
Most requests are for 5/16" thickness, although 1/4" or 3/8" are also very common. We stock more 5/16" but we can fill your order in any required thickness.
T-handles, 7 handles, and Straight handle. We can also make custom handles for you.
Absolutely, we can customize your blind in almost any way you need, just let the sales representative know when you place your order.
We stock our isolation and hydrotest blinds with a mill finish and offer a 125/250 RMS serrated finish as a standard option, but we can manufacture to your exact request/needs!
The term "paddle blind" is generic term and does not imply thickness or purpose of the blind (isolation or testing).
A "hydroblind", also often referred to as a "spec blind" or "hydrotest blind", is designed to handle the maximum pressure a pipe would be subjected to for testing purposes per ASME specifications.
Depending on the company, some use only hydroblinds for isolation Or testing as they consider this a safer way to operate. This way they know it will hold up if latent pressure builds up in the line. The hydroblind will not fail in this situation, where a thin isolation blind could if the pressure raises high enough.
This is dependent on the flange's AMSE rating. Sizes and thickness are manufactured to the ASME 16.48, API 590, ASME 16.5 specifications and will hold the pressure that the spec calls for.
Some other names we've heard a paddle blind referred to are: skillet blind, pancake blind, slip blind, test blind, hydroblind, hydrotest blind, spec blind, isolation blind, blank, and stop blind.

Of course! We regularly manufacture blinds out of more than 20 different materials, and we can make them out of practically any material at your request.
We use the handle colors as a quick way of identifying the flange rating for our blinds from a distance.
