If assembly breakage is incurred use a compound having higher elongation or use a two-piece piston. † This groove width does not permit the use of Parbak rings. For pressures above 103.5 Bar (1500 psi), consult Design Chart 5-2 for groove widths where Parbak rings must be used.

5.31.3 O-Ring Glands for Pneumatic Floating Piston Ring Seals Design Chart 5-3 provides the basis for calculating gland dimensions. For standard O-ring sizes, these dimensions have been calculated and are listed in Design Table 5-3. The procedures for the use of Design Table 5-3 are outlined in Design Guide 5-3.
