Frequently Asked Questions
Q: What are the specifications of the CT 3H1461 quad ring seal kit?
A: The CT 3H1461 is a quad ring seal (X-ring) manufactured from NBR 75 durometer elastomer per ASTM D2240. It has a 34.52-mm inner diameter and a 3.53-mm cross-section, meeting AS568-220 specification. The seal is rated for 1500 PSI static pressure and 900 PSI dynamic pressure, making it suitable for pump and heater group sealing applications in Caterpillar hydraulic systems.
Q: Which Caterpillar hydraulic applications use the CT 3H1461?
A: The CT 3H1461 quad ring seal is designed for pump and heater group applications in Caterpillar industrial equipment hydraulic systems. Quad ring seals (X-rings) provide superior sealing compared to standard O-rings due to their four-lobe design, reducing leakage and improving performance under pressure cycling. Verify your system pressure rating and seal cavity dimensions match before ordering.
Q: What are the cross-reference and superseded part numbers for the CT 3H1461?
A: The CT 3H1461 is the OEM Caterpillar designation. It supersedes part number 2H5325 and is equivalent to CTP 144828. An alternate designation is 3P1461. Always confirm the correct part number when ordering replacement seals, as using incorrect seal sizes or materials can result in hydraulic leakage or system failure.
Q: Why is a quad ring design better than a standard O-ring for this application?
A: Quad ring (X-ring) seals have four contact lobes instead of the single contact line of an O-ring, providing better sealing with lower friction and reduced heat generation. This design excels in pressure-cycling applications like pump and heater groups, extending seal life and reducing leakage under dynamic conditions. The CT 3H1461 quad ring is engineered specifically for these high-duty hydraulic applications.
