How do I get a hose on a fitting?

Stop by your local boat store and pick up a nylon 1.5" fitting...the barbs on those are 1.5". Not sure what you mean here. The one fitting is the plastic 1" - 1 1/2" adapter that I bought at a marine store (and it says "1 1/2" right on it!). The other is the existing brass suction-break that was used with 1 1/2" diesel filler hose. Never mind what it says...measure the OD. You'll find that nominal (what it's supposed to be) and actual (what it is) aren't always the same. PVC plumbing fittings aren't made just for the marine industry...they're the same PVC fittings that are used throughout the plumbing industry. I've never found anyone who knows the reason for it, but ALL gray pvc 1.5" thread x 1.5" barbed fittings are actual 1 5/8" barbed. But they're all marked 1.5 x 1.5. This is only true of 1.5"...for all other sizes, nominal and actual are the same. What's more, plumbing fittings--PVC, bronze, or anything else--aren't made to aerospace tolerances...wall thicknesses of two "identical" fittings can vary by as much as 50%, which can affect the ID, OD or both. And OdorSafe hose is so stiff that even a 1/16th an inch can make it very hard to get onto one. However, nylon and marelon fittings are made specifically for the marine industry...and nominal 1.5 x 1.5 fittings are ACTUAL 1.5 x 1.5. Btw...you said brass...most marine fittings are bronze. If it really IS brass, I wouldn't use it in a sanitation hose...urine is corrosive and brass is likely to get clogged up with vertigris. Warm the hose--don't overheat it!--and put a little dish soap on the inside of it and on the fitting. You should be able to get it the hose onto it. I can. Thanks - I'll try it! If I can't, can you make a house-call to Vancouver, Canada? Sure, if you'll pay my travel expenses! Not sure I can get a hairdrier at this hose. Lloyd, if you can get at it to work on it, you can get a blow dryer close enough to it to warm it a bit. That's why they make extension cords. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://shop.sailboatowners.com/detai...=400&group=327 http://www.seaworthy.com/html/get_ri...oat_odors.html |
