Maintain system integrity and prevent costly leaks with the genuine Armstrong AS1270-375 O-ring. Designed for precise fitment in hydronic applications, this replacement component, identified by part number AS1270-375, serves as a critical barrier to ensure fluid containment within your Armstrong equipment.
This EPDM O-ring functions by providing a high-compression seal between mating surfaces, compensating for thermal expansion and mechanical vibration to prevent fluid bypass. Its resilient material composition allows it to withstand consistent pressure fluctuations, ensuring long-term operational reliability in demanding climate control systems.
Key System Performance Baselines:
- Material Composition: High-grade EPDM rubber for superior chemical and heat resistance.
- Precise Dimensions: Engineered with a 9.475-inch inner diameter and 0.210-inch cross-section for a perfect seal.
- Reliable Maintenance: Designed for easy installation during standard pump or valve servicing.
⚠️ Application Profile: Recommended for use in HVAC hydronic heating and cooling systems, municipal fluid transport, and commercial pumping stations where reliable sealing is required for Armstrong equipment.
