Key Advantages of 1T1639 (2035958) Seal Kit
What distinguishes the 1T1639 kit from single-material or single-shape options is its strategic combination of O-rings/D-rings and NBR/FKM. O-rings excel in static pump housing seals, while D-rings—with their flat contces—provide enhanced stability for rotating shafts, reducing twist and wear. NBR components offer superior resistance to mineral oils and greases for low-to-moderate temperature zones (e.g., pump casings), while FKM variants handle high-heat sections (e.g., pressure relief valves) with oxidation and chemical resilience. Each seal is precision-machined to tight tolerances, ensg a perfect groove fit. This synergy makes the 1T1639 kit cut pump-related hydraulic failures by up to 45% compared to generic seal sets.
Technical Specifications of 1T16391T1639
Temperature Range: NBR seals operate from -25°C to +125°C (-13°F to +257°F); FKM seals function from -15°C to +200°C (5°F to +392°F), covering all pump heat zones
Pressure Rating: Both O-rings and D-rings withstand up to 6,000 psi (414 bar), exceeding the pressure demands of most excavator/loader
Material Benefits: NBR has 35% better oil resistance than natural rubber; FKM offers 40% higher heat resistance than nitrile; D-rings reduce shaft wear by 25% vs. O-rings
Kit Inclusions: Assorted NBR/FKM O-rings & D-rings (pump-specific sizes), anti-extrusion backup rings, groove cleaning tool, high-temp seal lubricant, and a pump model compatibility chart
