Mechanical Face seals are fitted in a Groove of retaining housing, to form the sealing at the adjoining faces. Metal faces are precision Lapped. The ramp angle of Seal and Housings are slightly different and form a wedge for the rubber ring to slide into and form a compressed profile giving load on the seals and making it intact. The installation guidelines are aimed to protect the precision lapped and Functional metal sealing faces. The more precautions taken, the more Likely the seals will last in the field.
