$5.04
Manufactured to Cat OEM specifications, the AFA Industries 5H7704 O‑Ring matches Cat part 5H‑7704 precisely. With a 94.61 mm (3.725") inner diameter and about 7 mm cross-section (0.28"), this silicone seal (Shore 70A) resists temperatures from –50 °F to 300 °F. Engineered for static applications like air seals or grease/oil protection, this ring delivers reliable OEM-level sealing where Cat uses dash‑128 silicone O‑rings.
Specifications
The AFA Industries 5H7704 silicone O‑Ring seal is engineered as a direct replacement for OEM Caterpillar part 5H‑7704, favored for static sealing in air, electrical systems, or grease interfaces. Measuring 94.61 mm (3.72″) ID and ~7 mm cross-section, it meets Cat's dash‑128 standard and is molded from VMQ silicone (Shore 70A) to resist thermal extremes and ozone exposure. Rated for –50 °F to 300 °F (–46 °C to 150 °C), it's not compatible with diesel, coolant, or hydraulic fluids. Lightweight and compact, it seals components reliably in industrial and Cat-specific environments. Widely stocked by suppliers such as Interstate‑McBee (M‑5H7704) and heavy-duty parts dealers.
