24° Cone and O-Ring Seal for Leak-Proof Reliability
The 24° cone and O-ring seal combination delivers exceptional leak-proof reliability. The metal-to-metal contact of the cone provides a strong primary seal, while the O-ring offers a secondary barrier against fluid escape. This dual-seal approach ensures consistent performance, even under high pressure and temperature fluctuations.
- Cycle testing of six samples (sizes 6, 8, and 16) demonstrated 1 million cycles to peak pressure with no damage or leakage.
- Fatigue testing of SAE J2337 fittings (sizes 6 and 8) in aluminum hydraulic pump housings showed no failure up to 26 million cycles, outperforming O-ring boss ports which failed around 400,000 cycles.
- Pressure capability tests support working pressures up to 12,000 psi with a design factor of 4:1.
- The double seal design, combining a 24° conical metal-to-metal seal and a radial O-ring with zero clearance in the groove corner, provides extrusion resistance and leak-proof performance.
- Comparative benchmarks show the SAE J2337 fitting reduces forces acting on the port by approximately 100.5%, enabling use of lighter materials like aluminum at higher pressures.
- The design eliminates the need for adapters, reducing potential leak points and simplifying assembly.
- The fitting system exhibits superior fatigue life, higher pressure capacity, and zero leakage compared to traditional O-ring boss port fittings.
These results confirm the 90°METRIC FEMALE 24°CONE O-RING H.T. ISO 12151-2–DIN 3865 fitting’s ability to maintain a secure seal, even after millions of cycles in demanding hydraulic environments.
