Stopping the flow in a piping system or isolating a pipe section is often necessary for repair or maintenance or for pressure testing. One of the quickest and easiest ways to do this is with paddle blinds. When you need high-quality paddle blinds and other isolation piping products, turn to our team at Hydro Blind Solutions.
We offer sales and rentals of paddle blinds designed for isolation or hydro testing, and we feature high-quality alloys for the ultimate in strength, durability, and corrosion resistance. Our company has over four decades of experience, and we ship industrial pipe products throughout the continental United States as well as globally.
What Is a Paddle Blind?
A paddle blind features a circular plate that blocks the flow of fluids or gases in a pipe, along with a T-shaped or skillet-like handle that allows for easy maneuverability. It’s bolted between two pipe flanges with gaskets on either side to effectively seal off or isolate that section of pipe for maintenance, repairs, or pressure testing.
At Hydro Blind Solutions, we feature paddle blinds manufactured from carbon steel, stainless steel, or specialty alloys to meet all your industrial pipe needs.
Depending on the pipe size, class, and application, paddle blinds are available in thicknesses that range from a quarter-inch inch to 7 inches for ASME B16.48 blinds. Isolation paddle blinds are available in a thickness of five-sixteenths of an inch.
At Hydro Blind Solutions, we offer cost-effective paddle blinds with a mill finish that provides a flat face for easy sealing. We also offer machined finishes for ring-type joints. We offer sizes from half an inch in diameter up to 60 inches, along with custom options.

Frequently Asked Questions
How do paddle blinds work?
Paddle blinds work by being bolted between two pipe flanges with gaskets on either side. This effectively blocks the flow of fluids or gases in the pipe, allowing for maintenance, repairs, or pressure testing without disrupting the entire system.
How do I determine the right size and thickness for my paddle blind?
The size and thickness of a paddle blind depend on the pipe size, class, and application. It’s essential to refer to the ASME B16.48 standards or consult with experts at Hydro Blind Solutions to ensure you select the right product for your needs.
When would I need to use a paddle blind?
Paddle blinds are commonly used during maintenance, repairs, or pressure testing of a piping system. They allow for the safe isolation of a section without having to drain or shut down the entire system.
What’s the difference between a paddle blind and a figure 8 blind?
While both are used for isolating sections of a pipe, a paddle blind is a solid plate that completely stops the flow. In contrast, a figure 8 blind (or spectacle blind) has one solid section and one open section, allowing for easy switching between blocking and allowing flow.
Can paddle blinds be used in high-temperature applications?
Yes, paddle blinds made from specific alloys can withstand high temperatures. It’s essential to choose a paddle blind material compatible with the temperature and pressure conditions of your system.
