[Public-list] Original gatevalve sizes

[sousa, stephen (ENG)]

Jack,

Back on topic, could one mate a bronze thru-hull with a brass ball-valve 
with some semblance of expectations of safety/durability?

I am not sure of the thread in Canada, in the US the answer is no. The
threads are different and do not mate exactly. Also a few years back, Apollo
had issues with using brass vs. bronze/chrome plated balls in their valves. 

I like Buck as a manufacturer, the entire assembly is bronze with the
exception of the handle.

Gord,J

I'm 'round the corner in Penetang - Dutchman's Cove. No slip; winter 
there, then cruise 2-3 months full time.

Would that commercial plumbing supplier be St. Amant's, by any chance?

Will be down on April 20/21 to drop off new cushions and other bulky 
items before swinging down to Guelph to pick up my daughter from 
university.  Back in mid-May for much needed project work (and noted 
survey) and launch mid-June.  Superior, to Thunder Bay, is in the plans. 
  (Tested Whitefish Bay last year.)

Back on topic, could one mate a bronze thru-hull with a brass ball-valve 
with some semblance of expectations of safety/durability?

Cheers
Jack
