[INQ. NO. 2607M02] JEONG WOO COUPLING CO., LTD. showcased its next-generation pipe-coupling solution that simultaneously secures construction innovation and seismic performance at ENVEX 2026, Korea’s representative environmental and carbon-neutral exhibition, recently held at COEX in Seoul.
Established in 1995, JEONG WOO COUPLING has dedicated itself to the production of pipe-connection couplings and leak-repair clamps. Recognized for its technological prowess, the company is a global powerhouse exporting over 70% of its production to approximately 40 countries worldwide, including Japan, the United States, the Netherlands, and the UAE.
Domestically, JEONG WOO COUPLING has developed unrivaled quality reliability through a wide range of delivery performance, spanning everything from large-scale plants for major corporations to small and medium-sized sites.
The pipe-coupling that JEONG WOO COUPLING introduced as its flagship product at this exhibition, is an innovative product that replaces existing complex and skill-intensive piping methods such as welding, flanges, sockets, and groove joints.

Notably, it requires absolutely no pre-processing steps, such as pipe threading or welding. With just a standard wrench, fastening can be done quickly and safely on-site, thus drastically reducing construction difficulty and significantly shortening the construction period — as well as reducing overall piping installation costs, including labor expenses.
Moreover, it can be applied to all pipes regardless of material — ranging from steel and stainless-steel pipes to cast iron pipes, copper pipes, plastic pipes (PVC, PPR, PE, etc.), and fiberglass pipes — providing exceptional flexibility even when connecting dissimilar pipe types.
JEONG WOO COUPLING’s technological prowess shines even in the harsh fluid environments and safety standards of industrial sites. This is because it is designed to allow for the selection and application of an optimal rubber gasket tailored to the type of fluid flowing inside the pipe.

Accordingly, stable installation is possible in various specialized piping systems carrying hazardous substances, such as oil and chemicals, in addition to water and air. Consequently, it is gaining attention as an essential piece of equipment across all industrial sectors, ranging from large-scale plant industries like shipbuilding, chemicals, steels, and power-generation to construction, civil engineering, and maintenance sites for various equipment and aging pipelines.
In addition, the rubber gasket installed inside the product flexibly absorbs noise, shock, and vibration generated during pipe operation. This perfectly meets the seismic design standards for piping that have recently been strengthened worldwide.
At the exhibition, a detailed product lineup tailored to various on-site requirements was also introduced, drawing keen attention.
First, the ‘Grip Type’ is a model equipped with a powerful anti-detachment function that prevents pipes from coming loose due to internal pressure or external impact, and is supplied in sizes ranging from 15A to 400A.
Also exhibited is the Slip/Flexible Type, characterized by its ability to flexibly absorb pipe movements by allowing for natural stretching and contraction. It features perfect manufacturing specifications ranging from small-caliber 13A to extra-large caliber up to 4,000A.
