Service life of hose
I am looking for some info on the normal service life of cotton jacketed and nitrile rubber fire hose to justify a grant request. Does anyone know if NFPA or any other agency addresses this and what specification it would fall under? Thanks.Thomas Anthony, PE

As far as I know,as long as it passes the annual service test it's good until such time as it doesn't.We've got some at thirty years old that still passes it's annual. Hope this helps,T./C.

Cotton jacket hose service life is twenty years.

I believe the manufacturers of the hose say figure on 10 year service life.09-11 .. 343 "All Gave Some..Some Gave ALL" God Bless..R.I.P.

Questions:Who still uses "straight"cotton jacketed and who definitively says twenty years service life? I know of many depts around here that are still using hose that dates back closer to the 30 year mark.And it still passes the annual pressure test.8-10 Years? I don't know of ANYONE around here replacing hose that regularly.The threads are great, they get you looking into things that might be of little concern otherwise. T.C.

There are a few lengths of deuce and a half "alligator" hose (heavy dual jackets, brass couplings) that were donated to the Mass Fire Academy that are still in service today!"The education of a firefighter and the continued education of a firefighter is what makes "real" firefighters. Continuous skill development is the core of progressive firefighting. We learn by doing and doing it again and again, both on the training ground and the fireground."

Weíre like you T.C.
Every year the hose get inspected for mechanical damage (this is a bit arbitrary I admit, what I think is bad abrasion you may consider OK) and then pressure tested. If it passes those tests then itís put back into service. Realistically, our hose gets mechanically damaged long before 30 years have passed.
If there is an end-of Ėlife spec on the hose I havenít heard of it. Maybe we donít ever reach it so it doesnít matter (we don't date the hose but we do track a serial number that we write on each lenght).

Gonz,I've probably still got a half a dozen lengths of that "flexible iron pipe" left around.It dates back to the late fifties/early sixties.You can't destroy it.I test my hose to the 250 level then it gets three minutes at 300,sorts out the marginal stuff.That old pipe with the brass couplings just aces the test,year after year.We used to have a '48 Chev that I think had about 2600' of that stuff on it.Truck went good but didn't stop so great(wonder why?).When the truck went a lot of that old hose "disappeared" and was replaced with red rubber 2".I've gradually got my hose loads back in balance now.

COTTON Jacketed hoseline??
We haven't used cotton jacket hose or bought it since back in the 1970's.
All our handline hoselines have 100% polyester thread, coated with a material that will keep the hose line from damage.
Supply lines are 4 inch, snap tite or other approve equal.
We had 100% cotton jacketed hose when I came on the job and when you used it and roll it up, it was twice the size of the newer hose. Winter time was hell to pay to get that old stuff up after a job.
Stay Safe and Well Out There....
