1/2" OD X 3/8" ID Stainless Tube Insert

The I-8-6 Tube Insert is an essential, high-precision plumbing component designed for heavy-duty instrumentation setups. Engineered with premium 316 stainless steel, this tube insert acts as an internal structural support sleeve when utilizing compression fittings with soft plastic, polyurethane, or thin-walled tubing. It ensures a highly stable connection, effectively minimizing potential leak paths and maintaining consistent flow dynamics under high system pressures and heavy vibrations.

Key features and benefits include:

• Leak Prevention Architecture: Provides the internal rigidity needed to ensure dual ferrule instrumentation fittings bite properly into softer tubing, preventing blowout or deformation.
• Premium 316L Stainless Steel: Forged to offer exceptional resistance to chemical corrosion, oxidation, and extreme temperature fluctuations.
• Tested to Rigorous Standards: Manufactured to meet strict ASTM F1387 specifications, validating dimensional consistency, material integrity, and long-term durability in critical fluid-handling environments.
