Looking For Slide Out Seal For 2013 Flagstaff 831RLBSS

Updated 05/13/2026 | Published 05/12/2026

Question:

Hi I have a 2013 Flagstaff trailer model 831RLBSS with 2 slides. My seals seem to slide on a metal track held to the wall with usual screws. I have 2 picts to identify and figure out which seal is right. Standard D bulb with 2inch wiper is attached. Probably could cheat with a 2 1/2. Almost every one is telling me this seal set is NLA. Even Forest River said we dont have and I asked about a updated seal with press on tape etc. Did not get a reply. Can you help?? Thank you Carl McClaflin

Hey Carl, thanks for reaching out. We may have the seal you'll need, but the only way to know for sure will be to look at the side profile and dimensions of the seal and try to find the closest match. There is no way to add pictures to the comments on here (yet), but if you can email those pictures to me I'm happy to take a look and see if we have anything.

For example, the Rubber Wiper Seal with Bulb for RV Slide Out # SR38FR is 2-7/8" tall and sounds like it may be similar to what you need. I've included a picture that shows the side profile and dimensions.

Does this look similar to what you have? If not, feel free to send me those pictures and I can take a look.

I do have 2 pictures clearly showing the seal and the track the D-seal slips into in. I need a email I can send to. I obviously been working on it to Here is the closest thing I can find. If Etrailer can find a better match? YEA!! Here it is: Combo RV Slide Out Black Rubbers | 018-312-EKD & 018-341 EK | 1' x 15/16' x 35' D-Seal Wiper & 1/2' x 2.75' x 35’ Seal Base | Works with Keystone, Forest River (018-312-EKD + 018-341 EK) This was from an Amazon reviewer who had a similar trailer---Mine is a Flagstaff 2013 831RBLSS Jesse if you need a VIN? No problem. Thank you for your help!!

@CarlM Hey Carl thanks for all that. I replied to your email but I figured I'd post it on here too. I think you are on the right track here with the 018-312-EKD & 018-341 EK you mentioned. Those original seals must have been discontinued because I'm also not finding an exact match anywhere. We offer a similar seal here but it's not going to be a direct replacement for the original seal. We have a similar D-seal part # SR74FR. Then our closest wiper seals are 2-13/16" long part # SR87FR so that might work as long as you don't think its too long.
