    Design: NB: Size Lists Give "On Line" Tolerances For Rod Applications

    Uploaded by

    Nal Fivefivetwoone
    The Hallite 15 rod seal is designed to provide an effective seal at both low and high pressures. It comprises a rubberized fabric U-ring for strength and durability, with a molded rubber header. The angled rubber lips are precisely machined to ensure a good seal at low pressure and deform under increasing pressure to seal more effectively. The fabric surface contains pockets that retain lubrication to reduce friction and wear. The seal is intended for use within specified operating conditions of speed, temperature, pressure, and gap tolerances.

    Design
    The Hallite 15 rod seal has been well proven in many applications requiring a compact, low friction seal to work
    efficiently both at low and high pressures.
    The seal comprises a rubberised fabric U ring to give strength and durability, to which is moulded a rubber header.
    It is designed to have a controlled pre-load across the angled rubber lips which are accurately machine trimmed,
    to ensure a good seal at low pressure.
    The seal becomes more effective as the pressure increases and the rubberised fabric deforms to the housing
    increasing the seal contact area. The surface of the fabric has pockets which retain lubrication to reduce friction
    and wear.
    The proportions of the range have been determined to give a satisfactory performance when used with the
    recommended operating conditions. Many other sizes are available outside this range.
    The range should be fitted to split housings as shown, but sizes marked* can be fitted to a grooved gland housing,
    if assembled with care.
    NB: Size lists give "on line" tolerances for rod applications.
