Description
The Armstrong Fluid Technology AS1270-237 is an EPDM cover O-ring designed for sealing pump side connections on 1-1/2", 2", and 2-1/2" suction guides. This precision sealing component helps maintain proper system integrity by preventing leakage at the cover interface in hydronic pumping systems. Manufactured from EPDM rubber, it offers strong resistance to water, glycol mixtures, and common HVAC system fluids, making it suitable for long-term use in commercial pump assemblies. It is commonly used during maintenance or rebuild of Armstrong suction guide components where reliable sealing performance is required.
