The "Double Nut MV" is a double nut type fitting for vinyl-coated copper pipes (control copper pipes). It has a structure that seals the copper tube part 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 that may enter from the outside, using 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" requires no processing on the pipe section due to the connection via rings (beads). 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. 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 ○ The pressure can withstand considerable pressure (2.94 MPa) due to the ring completely adhering to the pipe under internal pressure (for resin pipes, up to 0.97 MPa) ○ The operating temperature range is -45 to 150°C for copper pipes and 0 to 60°C for resin pipes For more details, please contact us or download the catalog.

The "Ring Sleeve MV" requires no processing of the pipe section due to its connection using rings (soroban beads). Tightening is achieved through a connection with a bag nut, eliminating the need for special tools, fire, or adhesives. After use, it can be easily removed and reattached for inspection or redecoration. 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 or 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 use is -45 to 150°C for copper pipes and 0 to 60°C for resin pipes.

The sleeve-type flare allows for tightening of the bag nut, which generates a clamping force that is transmitted to the contact surface of the pipe flare section through the sleeve. This means that rotational friction (twisting) forces do not act, allowing for 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 "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, flames, 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. ○ The pressure is supported by the internal pressure, allowing the ring to fully adhere to the pipe, withstanding considerable pressure (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.
