The "high-pressure valve" is designed with safety in mind as a certified high-pressure gas product. The handle has a smooth shape that makes it easy to operate. Additionally, it features a drainage hole, preventing rainwater from accumulating when used outdoors. The handle torque is light, and the design is compact. There are two methods for securing it: using the mounting screw hole at the bottom of the valve or panel mounting. 【Features】 ■ Easy-to-grip handle shape with excellent operability ■ Handle structure with a drainage hole ■ Uses SUS630 for the valve rod material, which is less prone to seizing at high temperatures ■ Compatible with both panel and bottom mounting ■ Operable with low torque *For more details, please request materials or view the PDF data available for download.

The sleeve-type flare allows for the tightening force generated by tightening the bag nut to be transmitted to the contact surface of the pipe flare section through the sleeve, which means that rotational friction (twisting) force does not act, enabling uniform tightening without damaging the pipe flare area, resulting in a leak-free conical seal. 【Material】 ○ Body: JIS H3250 C3604 or C3771 ○ Nut: JIS H3250 C3604 ○ Sleeve: JIS H3250 C5441 For more details, please contact us or download the catalog.

The double ferrule type for copper pipes is a structure that supports the tube with two ferrules: a front ferrule and a back ferrule, allowing usage up to about 1/4 of the breaking pressure of the copper tube. We offer a wide range of products tailored to various applications, including "male connectors (tapered screw type)," "male elbow connectors (tapered screw type)," and "female connectors (tapered screw type)." 【Materials】 ○ Body: JIS H3250 C3604 or C3771 ○ Nut: JIS H3250 C3604 ○ Ferrule: JIS H3250 C3604 For more details, please contact us or download the catalog.

The "Double Nut MV" is a double nut type fitting for vinyl-coated copper pipes (control copper pipes). It features a structure that seals the copper tube and the vinyl part with two separate rings, connecting the copper pipe without leaks using a brass ring, and protecting the copper pipe from substances that cause corrosion, such as water, dirt, and dust entering from the outside, with a resin ring. 【Materials】 ○ Main body: JIS H3250 C3604 or C3771 with nickel plating ○ Adapter: Adapter nut JIS H3250 C3604 with nickel plating ○ Ring-1: JIS H3250 C3604 ○ Ring-2: Resin (polyethylene) For more details, please contact us or download the catalog.

The "resin MV" does not require any processing on the pipe section due to the connection relying on rings (beads). Tightening is achieved through a connection with a bag nut, so no special tools, flames, or adhesives are necessary. After use, inspection, removal for redecoration, and reinstallation can be easily performed. The fittings are nickel-plated, providing sufficient corrosion resistance and an aesthetically pleasing appearance. 【Features】 - Usable with oil, water, air, etc. - Can be used with any fluid that does not corrode copper and brass. - Due to the internal pressure, the ring completely adheres to the pipe, allowing it to withstand considerable pressure (2.94 MPa) (for resin pipes, up to 0.97 MPa). - The temperature range for copper pipes is -45 to 150°C, and for resin pipes, it is 0 to 60°C.

The "Ring Sleeve MV" requires no processing of the pipe section due to the connection relying on the ring (bead). Tightening is achieved through a bag nut connection, eliminating the need for special tools, flames, or adhesives. After use, inspection, removal for redecoration, and reinstallation can be done easily. The joint is nickel-plated, providing sufficient corrosion resistance and an aesthetically pleasing appearance. 【Features】 ○ Usable with oil, water, air, etc. ○ Can be used with any fluid that does not corrode copper or brass. ○ The pressure can withstand considerable pressure (2.94 MPa) due to the ring fully adhering to the pipe under internal pressure (for resin pipes, up to 0.97 MPa). ○ The usable temperature range is -45 to 150°C for copper pipes and 0 to 60°C for resin pipes.

The "resin joint" requires no processing on the pipe section due to its connection relying on a ring (like an abacus bead). Tightening is achieved through a connection with a bag nut, so no special tools, fire, or adhesives are necessary. After use, it can be easily removed and reattached for inspection or redesign. Its small outer diameter and lightweight design allow for minimal space usage. 【Features】 ○ Usable with oil, water, air, etc. ○ Can be used with any fluid that does not corrode copper or brass. ○ Due to the internal pressure, the ring completely adheres to the pipe, allowing it to withstand considerable pressure (up to 2.94 MPa; for resin pipes, up to 0.97 MPa). ○ The temperature range for use is -45 to 150°C for copper pipes and 0 to 60°C for resin pipes.
