4. When the End Cap flange mates against the housing, be sure the O-ring is properly seated in the
groove and is not crushed outside the groove between the end cap and housing.
5. The end cap is secured to the housing by gently starting one of the clamps onto the 15-degree
tapered flanges. After both sides of the clamp have been started, seat the clamp with
progressively sharper taps using a soft mallet. Clamping hardware includes 5/16” titanium nuts,
bolts and washers, are shown in F
IGURE 5-9.
NOTE: Nylon shoulder washers, also included, are essential and must be
positioned between the titanium and bronze to prevent damaging
galvanic corrosion of the bronze, as shown in FIGURE 5-9.
