What do the threads of pneumatic connector 1, 2, 3 and 4 mean?

The scores of 1 and 1 are English 1/8.

2, 2 points is Britain 1/4.

3, 3 points is 3/8 of the British system.

4, 4 is English 1/2.

Calculation formula: x minutes =x/8 inches, everything else is the same. 3 minutes =3/8 is 3/8 inches, and 4 minutes =4/8 is 1/2 inches, which can be converted according to the formula.

Threaded joint refers to threaded pipe joint, which is the most common pipe fitting in industry and life. Threaded joints make the connection of pipelines easier, and the disassembly and replacement are easier, which greatly saves the cost of pipeline connection.

Threaded joints usually include threaded elbows, threaded tees, threaded loose joints, threaded pipe caps, threaded pipe hoops, threaded reducers, threaded plugs, threaded outer wires and core sleeves.

Threaded joints used in industry are generally made of high-pressure resistant metals, such as carbon steel, stainless steel, alloy steel and brass. The threaded joint materials used in daily life generally include PC, PVC, PE, PPR, etc.

Thread characteristics of pneumatic joint

1, the joint has high strength and good ductility, which can give full play to the strength and ductility of the reinforced substrate. The performance of the joint reaches the grade I joint standard in JGJ 107-2003, and it can be disconnected from the substrate.

2. The connection is convenient and quick, and the operation is simple.

3, the detection is convenient and intuitive.

4. The straight thread of the steel bar can be prefabricated, and the sleeve can be produced in the factory, which does not occupy the construction period and has high processing efficiency.

5. No electricity, gas, naked flame, no oil leakage and no pollution are needed during the construction connection, and the construction can be carried out all day.

6, strong applicability, flexible operation in a narrow field with dense steel bars.

7. Horizontal, vertical and oblique HRB335 and HRB400 steel bars with the same diameter or different diameter can be connected.
