NL4975: Marine Wet Exhaust & Coolant - Smooth Hardwall R1

NL4975: Marine Wet Exhaust & Coolant - Smooth Hardwall R1

NL4975 is a hardwall marine coolant and wet exhaust hose that is less flexible than our NL4940 Nitrile Multi-Flex or NL4970 Corrugated Marine Coolant/Exhaust. It is NOT designed for use with petroleum based products or in oily environments. It is also suitable for use as a general radiator hose or for various low pressure water transfer applications where unusual sizes are encountered. It is resistant to heat, weathering, ozone, antifreeze, and abrasion.

Construction: Tube: Black EPDM rubber. Cover: Wrapped, black EPDM rubber. Reinforcement: Steel wire helix between plies of synthetic fabric.

Typical Fittings: N68 T-bolt clamps, N73/N75/N77 Mikalor clamps.

Temperature Range: -40°C (-40°F) to +100°C (212°F)

Detail Comments: In larger sizes we recommend using our NL4970 with a corrugated exterior for added flexibility and ease of installation.

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