OVERVIEW: The RA1‑AS is a flexible, stainless steel braided EPDM rubber hose assembly designed for quick and reliable connections in hydronic and plumbing systems including fan coil and heat pump connections. These pre-fabricated assemblies are offered in fixed lengths from 12″ to 36″ in 6″ increments, eliminating the need for on-site measuring or cutting. Brass swivel MNPT fittings on each end allow for fast, tool-friendly attachment, making them ideal for field installations where time and reliability matter. The EPDM inner tube offers excellent resistance to water, heat, and chemicals, while the stainless steel outer braid enhances strength, protects the hose, and provides kink and fire resistance. Temperature -20°F to 200°F.
| FEATURES: |
| • Flexible EPDM rubber core: Resists heat, water, and many chemicals |
| • 304 stainless steel braid: Adds strength, fire resistance, and prevents kinking |
| • Brass swivel MNPT fittings: Enable easy and leak-free installation without twisting the hose |
