Product Questions & Answers

got a 1-7/8 inch line on my boat, is this hose actually 1.875 ID or is it one of those “close enough” sizes?

Question by: Rusty F on Jul 7, 2025, 7:12 PM

For sizing, the inside diameter is listed as 1.875 inch, which is the same as 1-7/8 inch. It’s intended for head and holding tank sanitation runs where that ID is needed.

does this hose hold up alright when you're winterizing with antifreeze? heard some hoses get stiff or crack after a season or two

Question by: Larry W on Feb 20, 2026, 6:05 PM

The tube and cover on this hose are specially compounded to handle winterizing with antifreeze, so running antifreeze through it during layup is not a problem. The material is built to resist that kind of exposure without breaking down over time. That said, self-draining installations are still the recommended setup for longest service life, even with a hose this tough.
