NL4925 is used in similar heater and coolant applications as our regular NL4905, however this version has a wire helix reinforcement to prevent collapse in tight bends or in vacuum applications (max 20 in/Hg). As with other silicone hoses, it will remain flexible and ageless after prolonged exposure to extreme temperatures, weather, or ozone - it will stay soft and pliable after years of use as compared to traditional rubber which will harden and crack. Silicone rubber is not for use with oil, however it will stand up to engine oil mist found in normal operating conditions. When installing silicone hose, N62ET extended liner gear clamps will prevent the soft cover from tearing during clamping/use. For larger sizes, use N68SL/N75CT spring loaded T-bolt clamps to maintain holding power as the hose is subject to temperature fluctuations. Always check clamps at intervals and ensure proper clamp torque ratings are followed.

Construction: Tube: Smooth silicone rubber. Cover: Wrapped finish, green silicone rubber. Reinforcement: Two plies of polyester fabric with a helical wire.

Typical Fittings: N62ET extended liner gear clamps and N68SL/N75CT spring loaded T-Bolt clamps. No barbed/sharp fittings that may cut the tube.

Temperature Range: -54°C (-65°F) to +176°C (349°F)

Cut Method: Sawzall or Hacksaw & Side Snips for Wire-Wear Safety Gloves
