coupling

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. In a more general context, a coupling can also be a mechanical device that serves to connect the ends of adjacent parts or objects. Couplings do not normally allow disconnection of shafts during operation, however there are torque-limiting couplings which can slip or disconnect when some torque limit is exceeded. Selection, installation and maintenance of couplings can lead to reduced maintenance time and maintenance cost.

    Anyone know a cheap source for foam close coupling washers?

    Cheaper than £1.50 each. Once you stock up by a decent amount (i do shedloads of toilets) you realise what a rip off it is. 15 of each plus VAT and postage from toiletspares comes to 55 quid. For a bit of foam.

I plan to drain the system down & cut it out and replace it with a Honeywell V4043H1056 zone valve. From reading the forum it seems that the Honeywell valve is the one to go for. What's...

    Extending a compression t with a slip coupler

    It has been suggested that where I have imoveable piping and I am fitting a compression t, in order to get the right fit I could cut a wider gap and include a slip coupler. The terminology may be variable (coupler, coupling, joint) but from what I can see of a slip coupler it appears to have no...
