Video Transcript for Review of BAK Industries - Tonneau Covers - PARTS-326A0004

Today we're taking a look at a replacement bulkhead seal for tonneau covers. This replaces the bulkhead seal for BAKFlip truck bed tonneau covers. It works with the BAKFlip F1, G2, BAKFlip HD, FiberMax, the VP, the CS, and the BAKFlip CS-F1. Basically what this does is it creates a seal between the tonneau cover and the truck bed, and that's all in an effort to keep out moisture from entering the truck bed at the bulkhead. It's really nice design. It's a direct replacement straight from the original manufacturer.

It has adhesive backing, so it's a peel and stick application. It measures 3/8 of an inch thick, by 5/8 of an inch wide, by 65 inches long and if you have some extra length, depending on your vehicle, it can be trimmed to fit.That's gonna do it for today's look at the replacement bulkhead seal for tonneau covers.

Very good replacement for the last seal I had. Hasn’t degraded at all and keeps most of the water out of the bed. 829776

Bought these to replace the bulkhead seal on my Bakflip MX4 and worked out great and has done a good job thus far keeping water out of the bed. Quick shipping as well. 674153

Not what I expected. Since described as manufacturer replacement, I was expecting the rubber ribbed bulkhead seal that originally came with the cover. What I received was a piece of foam that I could have purchased for less money at any hardware store. The video and picture with measurements on your website show the ribbed seal. Might work but have not tried yet. 671981

I spent a fair amount of time researching the internet to try and find the exact gasket that was supplied with my Gator Fx3 tonneau cover, back in 2015. The video on etrailer even showed the correct gasket - with the 5 ribs facing up. However, the gasket that arrived, while it appears to be suitable for the task, is not the gasket that I was expecting to see. I hope it works. 667914

I was extremely happy with both of my purchases from etrailer. I purchased a used bakflip HD Cs series and unfortunately the bulkhead seal and knobs to tighten the cover down were missing. Along with this the rods are missing I will be ordering from etrailer again very soon. Fast shipping as well. 332703

  • Replacement Bed Rail Trim for BAK Tonneau Cover on 2003 Chevy S-10
    I think you may be referring to the Bulkhead Seal for your BAKFlip Tonneau Cover, which we have available in the 3/8" thick # PARTS-326A0004 and the 1/4" thick # PARTS-326A0005. I'm not sure what exact model BAK cover you have so you will just want to measure your existing seal to determine the right replacement. This is the strip that gets attached to the bed rails on your truck.

  • Replacement Seal for BAKFlip Tonneau Cover on 2012 Chevy Silverado

  • BAK Bulkhead Seal For Use With Spray-In Bed Liner and BAKFlip Tonneau
    Yes. This seal will adhere to a spray-on bed liner and although the # PARTS-326A0005 can be used, I checked with Bak and they recommend using the thicker 3/8" seal # PARTS-326A0004 as the seal to use on spray-on bed liners for the BAK Flip series covers. If you have a different BAK cover, let me know and I can recommend the appropriate seal for your spray on liner.

  • Bulkhead Seal Recommendation for BAKFlip MX4 Tonneau
    We have two bulkhead seals for the BAKFlip tonneau covers. We have the part # PARTS-326A0004 which is 3/8" Thick x 65" Long and we also have the part # PARTS-326A0005 which is 1/4 inch thick and 65 inches long. Since I don't know which specific part number cover you have you are going to have to measure your current one and determine which is the correct size.

  • Does BAKFlip MX4 Hard Tonneau Cover BAK48602 have a Seal at the Cab Side for a 2018 Honda Ridgeline
    The front (cab side) of the BAKFlip MX4 Hard Tonneau Cover # BAK48602 for your 2018 Honda Ridgeline has a seal that, when the cover is properly installed, will keep out water. You could add additional material such as # PARTS-326A0004 but doing so may not allow the cover to close at the front properly.
