The world's smallest push-button non-spill coupling (joint connector) NS1 is now available!

A low-cost non-spill connector that eliminates liquid dripping during attachment and detachment! Suitable for ink and medical use too!

CPC's one-touch fittings (couplings) have a lineup of over 18,000 types. Among them, the 'push-button non-spill joint,' which is classified as the world's smallest and lightest (*), is a fitting that contributes to the miniaturization of final products without causing liquid drips during attachment and detachment. It can be attached and detached with one hand in an instant while under pressure, and it minimizes air entry into the line to nearly zero, preventing the solidification and deterioration of inks and other substances. If you are considering cost reduction and weight reduction for stainless steel couplings, we also offer fittings made from super engineering plastic polysulfone. For more details, please download the catalog. You can also view a demonstration at the link below. http://www.youtube.com/watch?v=R55q-mLkXE0 * World's smallest and lightest... as a push-button non-spill fitting with valves on both sides. As of 2019.

No liquid leakage, one-touch connection is possible.

A joint that minimizes leakage to nearly zero during attachment and detachment thanks to a non-spill valve. The non-spill design allows for connection under pressure, and it is made from glass fiber-reinforced polypropylene, making it compatible with many chemical substances. The one-touch button allows for one-handed attachment and detachment, and the color coding enables visual differentiation of piping. <CPC Plastic Joint Features> Lightweight and low cost. Rust prevention. Usable for both gases and liquids. All-plastic construction allows for disposability. Dust-free cleanroom compatible products are available for medical and precision machinery applications. The tube can rotate freely, reducing twisting and preventing tube disconnection accidents during use. In the valve-equipped type, liquids (gases) are automatically stopped even when detached under pressure. There are numerous couplings made from plastics that have been confirmed for safety, such as NSF standard C-2 and USP type VI, ensuring food safety.

One-touch connection is now possible.

The smallest and slimmest among CPC products, suitable for use in tight spaces. Prevents incorrect connections with lure locks. Features a mechanism to prevent damage to the extremely thin joint section, which is the biggest issue with small fittings (U.S. patent). Also available in all-plastic versions, including disposable options. There is a wall-mounted (panel mount) type available. Due to being made of resin, it is low-cost and compatible with extremely thin tubes. Products suitable for dust-free clean rooms are available for medical and precision machinery applications. <CPC Plastic Fitting Features> Lightweight and inexpensive. Rust prevention measures included. Usable for both gases and liquids. The tube can rotate freely, reducing twisting and preventing tube detachment accidents during use. In the valve type, even when removed under pressure, the liquid (gas) automatically stops.

On November 6th (Thursday) to 7th (Friday), 2025, we held the "Human Body Day 2025" at the NAC Image Technology Akasaka Multi-Purpose Space. We have uploaded videos of the highlights from each company and the presentations that took place on the day to our website. We encourage you to take a look. ---[Report on Human Body Day 2025 is here]------------------- https://info.nacinc.jp/jintaiday2025-report ------------------------------------------------------------------------- On the day of the event, participants were able to experience a wide range of products in a hands-on session format, including motion capture, force plates, eye tracking, and human body analysis software. We received numerous comments from attendees expressing high satisfaction, saying, "It was great to gain various information all at once," which makes us very happy. NAC Image Technology will continue to provide "valuable products to our customers." We hope you will join us for our next event as well.

The "Mechanical Stitch Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
