Frequently Asked Questions
Q: What is the material and hardness specification for the YL 0029301AG O-ring?
A: The YL 0029301AG is molded Buna-N (nitrile rubber) with a durometer hardness of 70 Shore A, meeting ASTM D2000 material standards. This hardness specification provides resilience under pressure while maintaining flexibility in sealing applications. AS568A dimensional standards ensure the O-ring cross-section and bore diameter are precise for Yale electric lift truck hydraulic boss fittings.
Q: What hydraulic systems and fluids does this O-ring seal?
A: The YL 0029301AG seals hydraulic connections in Yale electric lift truck hydraulic systems. It is suitable for petroleum oils, mineral-based hydraulic fluids (ISO VG 32 through 68), and standard industrial hydraulic applications. Do not use this O-ring in fire-resistant fluid systems or synthetic polyol ester applications unless material compatibility is verified with Yale specifications.
Q: Is the YL 0029301AG available in other durometer hardness ratings?
A: The YL 0029301AG is specified at 70 Shore A durometer. This is the correct hardness for Yale electric lift truck hydraulic boss fittings. Do not substitute O-rings with different durometer ratings, as they will not provide adequate sealing pressure retention or may cause leakage under system pressure. If your application requires different hardness, contact us with your equipment specification.
Q: What is the typical replacement schedule for this O-ring?
A: Buna-N O-rings typically function for 2,000 to 4,000 operating hours in standard hydraulic systems. Replacement intervals depend on fluid temperature, pressure cycling, and contamination levels. Replace the YL 0029301AG if you observe hydraulic fluid leakage around fitting connections or if system pressure drops without obvious hose damage.
Q: Does the YL 0029301AG meet AS568A and ASTM D2000 standards?
A: Yes. The YL 0029301AG meets AS568A dimensional standards for O-ring cross-section and bore tolerance. It also conforms to ASTM D2000 material specification for Buna-N elastomer properties and durometer rating. This ensures the O-ring will fit precisely in Yale boss fittings and perform within design pressure limits.
