Nickel-Plated Brass Compression Fittings for Copper Tubing
- For Use With: Air, Cutting Oil, Diesel Fuel, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Lubricants, Mineral Oil, Natural Gas, Steam, Water
- Temperature Range: -75° to 550° F, except 90° elbow adapters with BSPP threads are 0° to 170° F
- Tubing: Use with copper
- Specifications Met: DIN 3861, except nuts meet DIN 3870
With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings. They have a single sleeve (ferrule) made of plain brass that gently bites into copper tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. These fittings are also known as flareless fittings. All meet DIN standards for tube fitting dimensions.
