They are intended for
completely dust and watertight sealing of cables, conduits and pipes, for
example in cars, aeroplanes, ships, electrical and hydraulic equipment, enclosed apparatus and light fi ttings. Both materials are weather and
temperature resistant and can be used both indoors and outdoors.Advantages
? Fast installation — seals without tightening of the grommet? Permits vibration in cables, conduits and pipes without detracting from
the seal? The sealing diaphragm is punctured only when the cable is drawn
through – acts as a blind plug and is ready for installation? Approved for installation in ships? Each size has a very wide sealing range.? High degree of protection – IP67ApprovalsApproved by Lloyds Register of Shipping, Det Norske Veritas for marine and
offshore use, and the Swedish, Norwegian, Danish and Finnish national approval
boards for watertight penetration.Degree of protectionIP67 in accordance with IEC.
InstallationPress the grommet into
the hole. Puncture the diaphragm using the wires from which the outer sheath
has been removed. Pull the cable back gently
to lock it. The grommet is
ready.M10880M10890M10900LSB02788_11-2013 97Glands and grommets Cable grommetThorsman TET?RangeType Colour Dimensions?/B mm Hole1)? mmQty per

Good resistance to mineral oils. The effect of other
petroleum products, such as solvents, lubricating
grease and wax, is insignifi cant. Should not be used
in direct contact with petrol (gasoline).Being based on laboratory tests, all information should be regarded for guidance only. Temperature, duration of exposure, concentrations,
etc., severely affect the properties.
