Our products are made of high-quality materials sourced from leading companies in Japan and Thailand.

We always have a large inventory available and select the most suitable materials according to the customer’s drawings and specifications. In addition to products that conform to JIS standards, we can also propose new designs and plating processes to meet customers’ needs.
We conduct various inspections using measuring machines, such as 3D measuring machines. In addition, depending on the inspection item, visual inspection is performed one by one, and strict quality control is performed.

Union

Excellent air tightness (male screw) for refrigerant piping

A “union” is a joint (male screw) used for connecting refrigerant pipes. By attaching it to the end of a pipe and using it together with a nut (female screw), pipes can be connected and removed simply by rotating the fitting itself without rotating the pipe.
It is ideal for areas where gas welding is difficult and provides reliable connections without the use of expanders or welders. It is widely used for cutting, extending, and replacing existing pipes.


Material: Brass

In refrigerant piping, the slightest distortion of parts or minor flaws can cause refrigerant gas leakage. In addition to high-precision processing, we manufacture and ship the finished parts with the utmost care to avoid even a slight scratch.

Nut

Excellent air tightness (female screw) for refrigerant piping

A “nut” (female screw) for connecting to the flare union at the jointing part of the refrigerant pipe. By applying flare processing, the connection part is highly adhered and exhibits excellent air tightness.

We manufacture a variety of shapes and sizes and support various installation methods.


Material: Brass

In refrigerant piping, even the slightest distortion of parts and minor flaw can cause refrigerant gas leakage.
In addition to high-precision processing, we manufacture and ship the finished parts with the utmost care to avoid even a slight scratch.

Distributor

Air conditioner distributor that equally distributes refrigerant throughout each cooling pipe

A distributor is a device that distributes the refrigerant evenly to each circuit of the multi-tube evaporator. Installed at the outlet of the expansion valve or the inlet of the capillary tube.


Material: Brass ※ Copper plating is also possible

We manufacture small to large items on a one-by-one basis.

Orifice

Brass joint for welding copper pipes and connecting parts

An orifice is a pressure-reducing device that regulates the flow rate of refrigerants.
When the refrigerant flows through a small diameter hole, the throttling action reduces the pressure of the refrigerant gas.
It is also used for welding copper pipes and for jointing parts to distributors.

Inlet tube

Steel tubes for air compressors

An inlet tube is a tube that feeds refrigerant to the compressor at high or low pressure.


Material: Steel ※ Copper plating is also possible

We manufacture small to large items on a one-by-one basis.
We perform terminal processing, bending processing, special processing, welding, and surface treatment.
