Mating Dissimilar Material (Plastic/Rubber) Windshield Washer Lines

[NDL]

I have a 2013 Buick LaCrosse. I replaced the stock windshield washer pump: the stock line is made of corrugated plastic. Without getting into detail, I replaced the line coming out of the pump into rubber.

I want to join the rubber line coming out of the pump, and the factory corrugated plastic line. Here’s the problem: the stock GM line is corrugated plastic. If I put a vacuum line coupler between both lines, the plastic line is inflexible/rigid, and the line won't clamp down sufficiently to grip the coupler without leaking.

The corrugated plastic windshield washer line is hidden through the fender and up the cowl – it’s unreachable - otherwise I would just put rubber all the way through.

How would you join both hoses? Pictures included for reference

Thank you

(EDIT: The rubber line coming out of the windshield washer pump is on the left; the plastic corrugated factory line is on the right)

I would guess and adapter. Napa might have a kit or hose barb to remedy this.

I use heat shrink after a light smear of rtv on the corrugated pipe to repair washer lines like this.

Barb fitting that goes into both hoses and clamp it down. If you wan't overkill, get out out the o-ring kit and find an o-ring that fits inside a couple of the corrugations before clamping it down.

Thank you all, for your helpful suggestions!

This is good to know, I've never seen this "corrugated" rubber before. Interesting!
