What is a Paddle Blind
A paddle blind is used to stop flow between two flanges during maintenance. Insert your paddle blinds between two flanges (with a gasket on each side) to stop the flow of fluid or gas. It is common to replace your blind with a spacer blind when the line is open.

We ARE the manufacturer, not a reseller, and we have been providing slip blinds to the industry since 1982. Our blinds are not just "cut and shipped metal", they are provided as a finished product... We send every blind we manufacture out with perfect symmetry, clean edges, fresh paint, marked or stamped (for easy identification with the line size and flange rating), and with color coded handles for quick identification of the flange rating from a distance.
Additionally, 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.
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.
