EZ Vent® Slip Blinds
Also called Vented Blind Flanges, Vented Paddle Blinds, Vent Blinds, Bleeder Blinds and Ported Blinds. Our Blinds Make Downstream Work Safer by Venting Off Dangerous Pressure / Fluids - Available for Sale or to Rent
USA Industries' EZ Vent® Slip Blind is similar to a paddle blind, with one major difference, typical paddle blinds block flow on both sides of your flange, which can lead to pressure or fluid building up on one side of the flange, but this ventable blind allows you to block flow on one side of the blind while allowing access to relieve or purge the other side. As a result, downstream work is much safer in the event of a leaking valve upstream.
The EZ Vent Slip Blind, also called a bleeder blind, is useful when there is not a valve on your piping at a location near where you are working. A ventable blind is the easiest way to verify that there is zero energy in the line, to vent off any pressure that has leaked by upstream valves, or to create an entry point for hydrotesting.

Frequently Asked Questions
Yes, multiple ports can easily be added, and we can add them on both sides upon request! Please specify how many and whether you want them on the upstream or downstream side of the blinds on your quote request.
Sometimes. For every NPT or Socketweld blind, there is a minimum thickness required, which is also determined by whether or not the blind needs to be rated for pressure. We can easily make your blind thicker to meet custom needs.
No, since the smallest tap size is 1/8" NPT or SW (which would require a .410 hole) it would need to be a minimum of 1/2" thick.
No. Our internal standard is to place the port at approximately 180 degrees from the handle with no interference between the connection and the bolts. However, if you need the connection point in a different location on the blind, we can manufacture it to your specs.
When requesting an alternate port placement, we recommend that you specify where in relation to the handle you would like the port(s) to be located (ie. approximately 90 Degrees from handle) and note that the vent must be located between bolt holes.
Yes! We can completely customize blind thicknesses to your needs.
Our EZ Vent blinds are easily identified by the "V" notch that we place in the top of the handle.
We always identify the vented side of the EZ Vent blind for you by marking it "VENT" on the handle. If you would like us to mark it in some other fashion for your needs that's EZ!
They are available for either rental or purchase, depending on your needs. Some restrictions apply.
Yes, just let us know your requirements. We can completely customize our products to your needs, and we regularly finish our blinds with a Machined 125-250 rms finish or an RTJ (RJ) for the gasket area.
Absolutely. We manufacture our EZ Vent Blinds and Spectacle blinds in house, and we're happy to put a port in a spectacle blind of any size or rating.
