O-Ring Groove Design Calculator: Engineering the Right Gland Geometry the First Time

Correct O-ring groove design is a multi-variable problem with tighter tolerances than most engineers initially expect. Squeeze, gland fill, extrusion resistance, and tolerance stack-up all interact — and an error in any one of them can produce leakage, premature elastomer degradation, or catastrophic seal extrusion. Global O-Ring’s O-Ring Groove Design Calculator encodes the published design […]

Bonded Seals for High-Pressure Threaded Connections

Summary Introduction Threaded connections are widely used to contain pressurized fluids and gases in hydraulic, pneumatic, and fluid handling systems. As pressure increases, sealing reliability depends not only on material selection but also on how compression and load are controlled within the connection. Bonded seals address these demands by combining structural support with elastic sealing […]

Square Rings in Static Sealing Applications

Summary Introduction Square rings are often viewed as a simple variation of a standard sealing element, but their geometry changes how sealing force is distributed and how the seal behaves in service. Instead of relying on a rounded profile, square rings use flat sealing surfaces to create stable contact within the gland. This difference affects […]
