321SS Braided Metal Hose Assembly — Female NPT x 150# Flange

Description

The 321SS Braided Metal Hose Assembly – Female NPT x 150# Flange provides a flexible transition between a female-threaded connection and Class 150 flanged piping or equipment. 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
• Female NPT connection on one end
• Class 150 raised-face flange on the opposite end
• Hose IDs: 2", 2½", 3", and 4" (2" configurable online; 2½" through 4" require RFQ and engineering review).
• Overall length: 12"–240" in 0.5" increments

Applications

Typical uses include equipment connections, pump connectors, female-threaded-to-flanged transitions, HVAC and hydronic piping, air/water-compatible process service, and mechanical-room tie-ins. Steam service is not the approved online application path for this single-braid Female NPT x Class 150 configuration; use the steam-service selection page or submit an engineering RFQ.

Engineering Review

Final suitability depends on hose ID, operating pressure, temperature, media, movement, minimum bend radius, flange material, thread engagement, support conditions, and installation geometry. Do not install the assembly under torsion or use it to correct excessive piping misalignment.

Ordering Notes

Select the required hose ID and overall length. The displayed price is reviewed before fabrication. Double braid, 316 stainless steel construction, alternate flange classes, special cleaning, pressure testing, tagging, material certificates, and documentation packages are available through RFQ.
