321SS Braided Metal Hose Assembly — Grooved End x 150# Flange

Description

The 321SS Braided Metal Hose Assembly – Grooved End x 150# Flange provides a flexible transition between grooved mechanical piping and Class 150 flanged equipment or headers. The 321 stainless steel corrugated hose absorbs vibration, minor misalignment, and controlled movement, while the 304 stainless steel braid reinforces the pressure boundary.

Key Features

• 321 stainless steel corrugated hose core
• 304 stainless steel single-braid reinforcement
• Grooved pipe end on one side
• Class 150 raised-face flange on the opposite side
• Hose IDs: 2", 2½", 3", and 4"
• Overall length: 12"–240" in 0.5" increments

Applications

Typical uses include grooved piping connections to pumps, heat exchangers, skids, packaged equipment, process headers, HVAC systems, and hydronic piping.

Engineering Review

Class 150 identifies the flange class; it is not the direct PSI rating of the completed metal-hose assembly. Final suitability depends on hose ID, validated working-pressure data, temperature, media, movement, minimum bend radius, grooved-coupling compatibility, flange material, support conditions, and installation geometry. Do not install the assembly under torsion.

Ordering Notes

Select the required hose ID and overall length. The displayed price is reviewed before fabrication. Double braid, stainless grooved ends, alternate flange classes, special cleaning, pressure testing, tagging, material certificates, and documentation packages are available through RFQ.
