Procedure for determining seal ring wear Check the rotary joint regularly to determine seal ring (6) wear. As shown in Figure 1, the shoulder of the nipple will be exposed as seal ring wear occurs. Should the seal ring (6) wear away completely, the metal nipple can wear into the wear plate and eventually through it. This will result in a significant leak and create a hazardous condition. Lack of attention may require replacement of the entire rotary joint instead of just the seal ring. TABLE 1 MAXIMUM SEAL RING WEAR (R) Rotary Joint Size Seal Wear Step 1. Locate the shoulder that has been...
