321SS Metal Hose – 304SS Male NPT Ends, Single / Double Braid

Description

The 321SS Braided Metal Hose Assembly – Male NPT x Male NPT is designed for threaded industrial and mechanical piping connections requiring flexibility, vibration isolation, or controlled movement. The 321 stainless steel corrugated hose is reinforced with 304 stainless steel braid.

Key Features

• 321 stainless steel corrugated hose core
• 304 stainless steel braid reinforcement
• Schedule 40 Male NPT connections on both ends
• Configurable hose ID and overall length
• Overall length from 12″–240″ in 0.5″ increments
• Engineering review before fabrication

Applications

Typical uses may include HVAC and hydronic piping, air and water service, pump and equipment connections, process piping, and vibration-isolation connections. Steam service is not the approved self-service path for this Schedule 40 Male NPT family. The controlled steam path requires the approved double-braid construction with Schedule 80 Male NPT ends, or an approved Class 300/600 flanged configuration. Submit steam operating conditions through engineering RFQ before ordering.

Engineering Review

Final suitability depends on hose ID, braid configuration, operating pressure, temperature, media, movement, minimum bend radius, thread engagement, support conditions, and installation geometry. Do not install the assembly under torsion.

Ordering Notes

Select hose ID and overall length. Every order is reviewed before fabrication. Double braid, alternate fitting materials, special cleaning, pressure testing, tagging, material certificates, and documentation packages are available through RFQ.
