Is the EPDM Reinforced Straight Connector for Cooling System SUPERFLEX RADIATOR SAE J20 R4 compatible with ethylene glycol-based coolants and operating temperatures from -40°C to +125°C?

Yes. The EPDM Reinforced Straight Connector for Cooling System SUPERFLEX RADIATOR SAE J20 R4 is resistant to ethylene glycol‑based coolants and is rated for operating temperatures from −40°C to +125°C, making it suitable for automotive cooling systems across extreme cold and high‑heat conditions.

Can the EPDM Reinforced Straight Connector for Cooling System SUPERFLEX RADIATOR SAE J20 R4 withstand repeated sharp bends without collapsing or losing coolant flow?

EPDM Reinforced Straight Connector for Cooling System SUPERFLEX RADIATOR SAE J20 R4 can withstand repeated sharp bends without collapsing or losing coolant flow. Made from durable black EPDM rubber and reinforced with a textile braid plus a robust steel spiral, it is specifically engineered to prevent hose collapse even under sharp bends. The corrugated exterior permits easy bending and adaptation while maintaining internal passage for uninterrupted coolant flow. Additionally, the “soft” ends (without steel spiral) ensure secure, leak-free clamping at connections. Rated for use with water and ethylene glycol-based coolants from -40°C to +125°C and compliant with SAE J20 R5 standards, this connector delivers reliable, flexible performance in demanding cooling-system applications.
