Press-Pak Elite Heavy-Duty V-Packing
Series 148 : Press-Pak Elite Heavy-Duty V-Packing
The 148 Series Press-Pak Elite Heavy-Duty V-Packing is available in a variety of configurations. Each set includes a reinforcing female adapter, an energizing male adapter and one to four heavy duty intermediate seal rings, depending on need. These sets are designed for dynamic applications and composed of elastomer, reinforced with fabric intermediate rings with high preload. The multiple sealing lip arrangements provide long leak-free service life. They can be supplied endless or split for ease of installation.
The 148 Elite Series is an enhanced version of the 148 Series. It utilizes abrasion-resistant polyurethane seal rings, along with a robust, extrusion-resistant polyamide female adapter ring. The Elite Series is a preferred choice for older legacy presses due to its abrasion and extrusion resistance. This is available in standard and custom sizes up to 2100 mm in diameter.
