A question about glands 1

[Cutiee]

I don’t know if I’m in the right section, but please help me if you could thanks

My question is:

Is single compression gland another name for stuffing gland? People seems to use the words stuffing glands all the time at my work, they never used the words single compression or double compression.

just a few days ago I had to order some glands, in my ordering spec I specified single compression glands(because I always think single compression gland is stuffing gland) but when I got the quote they didn’t quote me stuffing glands. Am I wrong to think they’re the same, or some people just don’t know it?

Should I just use stuffing glands in the order spec in the future?

Many thanks

The context may depend upon the type equipment, geographical issues, and more. The term gland is common for some British electrical fittings. Fisher use the term screwed gland for a screwed connection holding the packing follower in some rising stem control valves on page 50 of the Fisher Control Valve Handbook (page 62 of the PDF).

As JL above replies the term 'Gland' is used for a number of different engineering applications.

A compression gland could be an term used for a compression fitting on a water or pnuematic line,

Electrical s.w.a is terminated with glands these are sometimes called a compression gland because they compress and support the s.w.a when tightened

A stuffing gland will almost certainly be some form of seal

Such as on a boat, a stuffing gland allows the prop shaft to pass through the boat hull without the water entering the boat too much

A stuffing gland is fitted to the top of every control valve to permit the valve stem to rise and fall but retain the process fluid

hope this helps
