NL3420: Interlock Metal Hot Tar & Asphalt Hose

NL3420: Interlock Metal Hot Tar & Asphalt Hose

NL3420 is a stripwound galvanized metal hose that is manufactured by spirally winding a preformed continuous metal strip (0.030" thick). A special high temperature packing allows this hose to be used for suction or discharge up to 100 psi and for use up to +232°C (450°F). Our NL3420 Heavy Duty version is made from 0.030" thick metal strip and the NL3421 Light Duty is made from 0.018" thick metal strip. Standard lengths are 20ft (others available from the factory) with reusable solid male NPT (N342xMR-xxxMI) or swivel female pipe ends (N342xFR-xxxMI). DO NOT twist the hose during installation as it will cause the hose to unwind and result in leakage/failure. DO NOT flush with diesel or fuel as it will degrade the packing material.

Construction: Slightly ribbed, stripwound galvanized metal hose with a high temperature packing. The NL3420 Heavy Duty is made from 0.030" metal strip and the NL3421 Light Duty has a 0.018" thickness.

Typical Fittings: Specially designed reusable fittings for metal hot tar & asphalt only. DO NOT twist the hose during installation.

Temperature Range: -29°C (-20°F) to +232°C (450°F) under continuous service.

Warning: Must be packaged safely to prevent damage in transit

Cut Method: Abrasive Chop Saw // Wear Ear & Eye Protection
