Typical seal differences behind legacy gland names
- A1 / A2 glandThis term
The example contrasts a basic non-armoured entry with an outer-sheath-sealing construction. Check the supplier drawing and actual retention or sealing functions.
- BW / CW gland
The common distinction is the outer-sheath environmental seal. Both illustrated concepts have an armour interface, whose actual dimensions and duty need verification.
- C-type / E1 gland
The example distinguishes outer-sheath sealing from separate inner- and outer-sheath seals. Confirm both cable layers and the exact construction rather than relying on a legacy label.
Legacy paired labels often distinguish a basic entry, an outer-sheath seal and additional inner-sheath sealing. Armour termination is a separate interface in the armoured examples.
Typical conceptual distinctions, not universal definitions of every manufacturer model. Obtain the exact construction drawing and declared functions; the label alone proves no IP, retention or Ex rating.
