Looking for Replacement Rubber Hollow Bulb Seal for RV Slide Out
Updated 12/08/2025 | Published 11/24/2025
Question:
I am trying to locate a seal for under my 2009 Winnebago Access slideout. It appears to be a bulb type seal that fits over a flange. The OEM part is 159111-04-U01 EA TRIM/ZEE. Would CS45VR work? I only need the center since the ends appear intact. Thanks!

Hey Frank, I am not able to find any of the details on the 159111-04-U01 EA TRIM/ZEE that you need so what I would recommend is to measure the bulb seal and compare it to the # CS45VR and see if it would work. It's a 7/8 inch wide bulb that presses on so if that checks out this would work great for you. If you have something different let me know and I'll see if we have a solution.

Hey Frank, did the 7/8-inch bulb seal end up matching the one on your Winnebago Access slideout? Once you compared the measurements, it’d be great to hear if it worked for the center section. Your update could make it easier for others replacing a similar seal.
