Industrial Steam Hose Fitting

The Zoro Select 3LZ72 is a barbed hose fitting built for 3/4 inch steam pipelines. It connects air, water, fluid petroleum, chemicals and steam lines in industrial and automotive maintenance settings. The 1-inch NPT thread mates with standard pipe threads for a leak-free seal. Mechanics and plant technicians choose it for reliable fluid transfer.

Installation Notes

Thread the NPT end into the female port using appropriate sealant to prevent leaks. Push the 3/4 inch barb fully onto the hose and secure it with a clamp rated for the system pressure. The zinc-plated Q235 A3 steel resists corrosion but requires correct torque and clamp tension to avoid weeping. Improper hose preparation is the most common cause of failure.

Capacity and Limits

The 3/4 inch barb handles standard steam, air, water and petroleum lines within the fitting's pressure class. The Q235 A3 steel body and zinc plating withstand typical industrial temperatures and chemical exposure. Service life varies with cycling frequency, fluid aggressiveness and ambient conditions. It is not suited for diameters larger than 3/4 inch or for applications exceeding the fitting's rated pressure.

Questions about this item

How can I verify the Zoro Select 3LZ72 is sealing correctly after installation?

Pressurise the line with the intended medium — air, water, fluid petroleum, chemicals or steam — and inspect the 1-inch NPT threads and 3/4-inch barb for any sign of leakage; a leak-free seal confirms proper operation.

What comes with the 3LZ72 fitting and what must I source separately?

The package contains the single zinc-plated Q235 A3 steel barbed hose fitting with 1-inch NPT thread; you will need to supply the 3/4-inch hose, clamps or ferrules, and thread sealant or tape for the NPT connection.

Which version of this fitting should I choose for my 3/4-inch hose and 1-inch NPT port?

The 3LZ72 is the only model listed; it matches a 3/4-inch barb to a 1-inch NPT thread, so select this fitting when those exact sizes are required.
