Viega, a global leader in press connection and piping system solutions, is launching Cleaned and Bagged, a line of press fittings and valves that are cleaned, inspected and individually sealed through Viega’s quality-controlled process. Designed for demanding high-purity applications, Cleaned and Bagged combines controlled cleanliness with the speed and reliability of proven Viega press technology. The new line gives contractors, engineers and facility teams greater confidence in installations where system purity is a necessity and speed is critical. Viega’s Cleaned and Bagged systems can directly impact safety, product quality, and long-term system reliability with an industry-leading warranty on these parts.

Viega’s Cleaned and Bagged products are cleaned to Cleaned for Oxygen Service (CFOS) requirements*, providing a recognized cleanliness benchmark while supporting applications beyond the traditional scope of CFOS, including laboratory gases and other high-purity systems. The products follow established industry cleaning practices designed to reduce contaminants that could affect sensitive systems, including particles, hydrocarbons, volatile organic compounds (VOCs), silicone, salts, chlorides, fibers and corrosion products.

Each fitting and valve is cleaned, inspected and individually sealed in a controlled environment meeting ISO Class 8 cleanliness requirements or better, providing a ready-to-install solution for environments where cleanliness and installation efficiency are critical. Individual packaging helps protect components from contamination during transportation, storage and jobsite handling, maintaining cleanliness until installation while reducing jobsite preparation and supporting controlled installation workflows.

The product line is designed for a wide range of applications where maintaining system cleanliness helps preserve fluid purity and operational reliability, including pharmaceutical manufacturing, semiconductor and microelectronics facilities, research laboratories, advanced/precision manufacturing, industrial gas distribution and lithium battery manufacturing, among others.

“We designed Cleaned and Bagged as a scalable extension of our proven press systems,” said Lars Erkelenz, vice president of product management from Viega North America. “It gives contractors and engineers access to components prepared for controlled environments without sacrificing the speed, consistency and confidence they expect from Viega press technology.”

Erkelenz continued, “By managing the cleaning, inspection and packaging process, Viega gives customers greater control and confidence in every component, compared with fittings cleaned on-site or after purchase. And because they’re compatible with existing Viega press tools, contractors can use the same crews and familiar installation process to help reduce labor requirements and schedule risk in demanding project environments.”

Viega’s Cleaned and Bagged systems support applications requiring purity levels up to 6N (99.9999%), including demanding manufacturing and research environments where purity is critical. Referenced cleaning standards include: ASTM G93, CGA G-4.1, CGA G-7.1, MSS SP-138 and ISO 8573.

Like other Viega press systems, Cleaned and Bagged eliminates the need for hot work while providing secure, consistent connections. The system combines factory-controlled cleanliness with flame-free installation, reliable press connections and reduced installation preparation, helping project teams maintain stringent purity requirements without sacrificing installation efficiency.
