New Product: Announcement
Hygienic Cupla

We are pleased to inform you that the new Cupla, Hygienic Cupla SEW Series have just been released. It is a quick connect coupling designed for easy connection and disconnection of food manufacturing piping. The main application and features are as follows:


Hygienic Cupla was born to solve the various troubles of ferrule joints at food manufacturing factories, i.e., it takes time to disassemble and clean, it takes time and effort to assemble piping, the clamps work loose and leaks, the packings can easily dislodge and become contaminated, overtightening the clamps cut the packing.
Hygienic Cupla solves these problems by its features unique to couplers.


1. Quick and easy connection and disconnection
It can be connected by just inserting the plug to the socket and twisting the “Safety lock”.
By twisting the “Safety lock” counterclockwise, the safety lock will unlock for easy disconnection.

2. Corrosion resistant
Stainless steel (JIS SUS316L equivalent) for the liquid contact parts, buffing (#400) to prevent propagation of various bacteria.

3. Easy to disassemble and clean
No tools are required for disassembling/assembling. Small number of components requires minimum effort when cleaning. No small parts to lose.

4. Materials conforming to safety standards
The seal material not only conforms to the Food sanitation Act of Japan, but also the US Food and Drug Administration (FDA).
