Viega 16423 Insert Stiffener 3/4 Inches Bronze Press-fit Crimp Fitting

Product Description

The Viega 16423 is a 3/4 inch bronze insert stiffener designed for press-fit crimp fitting applications in potable water systems. This component plays a critical role in maintaining the structural integrity of flexible tubing connections. When a press-fit or crimp-style fitting is applied to a soft or flexible tube, the tube wall can collapse or deform under compression. The insert stiffener slides inside the end of the tube before the fitting is crimped, providing internal support that keeps the tube round and ensures a leak-free, secure seal. Plumbers and pipefitters rely on insert stiffeners like the Viega 16423 whenever they work with PEX, PEX-AL-PEX, or similarly flexible tubing in residential and commercial plumbing installations. The 3/4 inch pipe size matches standard tubing dimensions used throughout radiant heating systems, domestic hot and cold water distribution lines, and hydronic piping layouts. Manufactured from bronze, this stiffener delivers strong corrosion resistance and long-term durability in wet environments where lesser materials would degrade over time. Bronze is a proven alloy for potable water contact, meeting the demands of both high-pressure and standard residential water supply systems. The press-fit connection type on Fitting Side A makes installation straightforward, reducing labor time on the job site. Viega is a globally recognized manufacturer of press-fit plumbing systems, and the 16423 is engineered to meet the tight tolerances required by professional-grade installations. Whether used in new construction or retrofit work, this insert stiffener ensures connections hold firm and flow paths remain unobstructed. Keep a supply of these on hand for any job involving flexible tubing and crimp-style fittings.

• Bronze construction provides superior corrosion resistance for potable water applications
