Description
304 SS HDPE Pipe Inserts for CTS Polyethylene Tubing
CTS Stainless Steel Insert Stiffeners are precision-made components designed for insertion into the inside diameter of CTS polyethylene plastic tubing used in potable water systems. Built with 304 stainless steel construction, these CTS SS HDPE pipe stiffeners reinforce pipe ends to prevent collapse and provide structural support during fitting installation.
Recommended for pack-joint and ring compression water service fittings, these water service fitting stiffeners create a stable internal surface that improves gasket sealing and connection reliability. Their crush-resistant design and retention dimples help ensure dependable performance in potable water applications.
Key Benefits of Polyethylene Tubing Collapse Prevention
- Prevents Pipe End Collapse: Acts as reliable polyethylene tubing collapse guards for CTS pipe.
- Recommended for Compression Installations: Recommended on all pack-joint and ring compression water service fitting installations onto polyethylene tubing or pipe.
- 304 Stainless Steel Strength: Corrosion-resistant 304 stainless compression inserts support long-term potable water use.
- Crush-Resistant Interlocking Tabs: Interlocking tab design resists crushing under compression forces.
- Secure Fit with Dimple Tabs: Dimples on the sides hold the insert stiffener in place to minimize fallout during installation.
- Improved Gasket Sealing: Extended length permits an even sealing surface for the fitting’s gasket.
- Low-Resistance Insertion: Tapered and fluted ends minimize insertion resistance and movement.
- Potable Water Ready: Designed specifically for potable water installations.
