Looking For Wiper Seal With Bulb For Slide Out On 2018 Grand Design Imagine 3170BH
Updated 05/01/2026 | Published 04/27/2026
Question:
I have a 2018 Grand Design Imagine 3170BH trailer. My wiper seal for the slide out is 12’ long and has come apart and needs to be replaced. Can you help me with the proper replacement part? I believe I need a bulb and wiper combo. I can send a picture if needed.

Hey Andrew, thanks for reaching out. We do offer the wiper seals with bulbs. We'll just need to make sure we can match it up with what you have now since these seals aren't make and model specific. The best way to do that is to take a look at the side profile of the seal and take some measurements.
For example, the Rubber Wiper Seal with Bulb for RV Slide Out # SR38FR fits a 3/16" flange and is 2-7/8" tall overall. I've included a picture with detailed dimensions for your reference. Please compare this to what you have and see if it matches. If not, let me know, or feel free to email me a few pictures of your seal along with the dimensions and I'm happy to look into it.
How may feet of seal do you need?

Hi Jesse, it looks those measurements match up with it, I need 25 total feet to do the sides and the top. Actually 24.5, but the extra half foot would be good just in case.
