Fitting fire hose to barbs

[Nick Gravagne]

Hi Will,

 


Glad to help. Do your end caps look like these?  Go to
http://www.amazon.com/gp/product/B000BQ7VPA (Genova #31814 1-1/4" White MPT
Plug)


 


The threaded portion (barbs?) fits well enough into the hose I.D. with a
little push, hammering, and turning with pliers. Fill up the threads with
plumbers putty (the old fashioned gray stuff) and get the cap started in the
hose. Through a combination of twisting, pushing and hammering with a small
dead blow the cap will insert all the way.


 


After you have the cap inserted about half way, the hammering technique
involves (assuming you’re right handed) gripping the hose firmly in your
left hand at the partially inserted cap thread area and tapping. Strange as
this sounds it will work. Use hose/band clamps to tightly secure.

Hi Nick:

 

Your comments are very timely, and I am grateful for having them.  My end
caps are supposed to be 1 ½” (See second paragraph below)

 

 

Thanks for your remark about your using the 1.25” stuff for the end caps.
I’ll head over to Lowe’s tomorrow morning and buy one or two barbs of that
size and see if that is going to be a workable solution in a test fitting.
If that seems to be the ticket, then I can go about securing some ones of
sufficient quality.  

 

 

 

Nick, how are you holding the hose to twist and hammer – by hand?  I was
finding that the hose wanted to fold over against the pressure of the barb
against it instead of staying straight on.  I have some large channel lock
pliers, so I will try that too.

 

 

 

Thanks again for your help, and any further comments you have would be
appreciated.  

 

Will
