Non standard tap gland +1 inch

The attached image show a tap gland more than 1 inch in diameter.
Is it possibly American?

Best. O-rings are simple to replace. See previous write ups from me on the subject.

I don’t think I read that post of yours

 

[S.P.S.]

Oh, thanks for the heads up David .



I dispair sometimes. DO NOT face the seat. Most are hard chrome plated and removing it ruins the whole tap. Modern taps seats are NOT designed to be re-cut.

Interesting, never knew this! I was always taught to face up with every washer.
That said, I cannot recall ever seeing a chromed tap seat?? By the fact you can see bare brass at the bottom of most taps seats and throughout the whole internal tap area, I presumed no such coating was applied internally.
Plus, when do they cut the thread? Before or after coating? As again, usually you see bare brass threads. Not being smart here, just intrigued!

I will make sure I review this when I next have to rewasher!

Hi Stu.

It depends on the manufacturer. Hard chrome plating is not the same as bright chrome plating and is also rarely chrome coloured.
Back in the day, like eeeven older than me at 62, tap seats were deliberately raised up so they could be maintained. The valves used were also designed to accommodate that.

Actually they had that as part of their design because originally washers were leather. When the washer wore, inevitably the seat would be scored so it would need to be flattened again by re-seating.
Then, sorry I don't know when, rubber replaced washers. As far as I can estimate that would be around the early 1900s. In 1954 Alfred Moen invented the no drip tap because of leaking leather washers - but that was the USA!

Once production began to move to China in the 1970 & 80s, cost reigned supreme and they found that raising the seat up used more material so the practice of designing to repair was stopped - bloody accountants. Take a really old tap and you'll see a raised seat. Take a cr4p new tap and you'll often see a sunken seat. Manufacturers don't want taps being maintained they want 'em replaced.

Sorry I'm such a boring s0d

It's not boring mate, it's interesting, I have never heard anything like this before, as this never gets mentioned in college, or in onsite training!
As I often explain to my apprentice, you are constantly learning in this job, anyone who knows it all, is a DIY "you tube engineer" by trade......

Thanks for all the advice.
A different supplier to the other we asked has called it an 'exotic', "a one inch spindle, not locally available". I'll do some more research
