Why do EATON have many sealing ranges for the same gland size, whereas CMP glands have one sealing range? What are the advantages/disadvantages on this?

  • Of the three M25 sizes Eaton offer, the first two look to be cover the same range as the two larger M20 sizes - so I suppose are useful where you have a smaller cable but a larger hole.


    The (only) M25 size from CMP looks to be broadly similar to the largest M25 from Eaton.


    So if you were in the situation of having to put a smaller cable in an M25 hole, with Eaton you could get a gland to fit, with CMP you'd might have to find an additional M25 to M20 adaptor.


    You pays your money and takes your choice.
