Annular Construction
MSS4/CF04 (304 Series)
MSS6/CF16 (316L Series)
Features & Benefits
Wide temperature range -460ºF (-273ºC) to +1500ºF (+816ºC)
High quality and excellent workmanship to meet the rigorous demands of extremes in service at competitive prices with quick deliveries
-Machined bar stock end fittings; designed to mate with hose for proper weld techniques
-Double-pass welding (TIG)
-Custom fabrication available to meet customer specifications
More corrugations per foot
Greater flexibility than competing products of similar size
Low force to bend; easier to install and disconnect
-Flex-life extended
Compensates for misalignment, facilitates movements/thermal expansion
-Braid coverage engineered to contain the inner core under pressure and reduce possibility of squirm
Absorbs vibration and deadens noise in rigid systems
Vacuum tight
Handles high pressures
Corrosion resistant
Non-aging/non-flammable
All braid reinforcement is 304 stainless steel.

Details
Construction:
Inner metal hose:
-Annular corrugated close pitch hose
-Profile: parallel corrugations, omega shape close pitch
-Made from butt-welded tubing
Reinforcement: Polypropylene braid
-Each strand of large diameter (denier) polypropylene monofilament is twisted and subsequently twined prior to braiding
-Tested for maximum abrasion and chemical resistance
Fittings:
Any style using butt weld construction (TIG method)
-
NPT FNTP. flange. J.I.C. compression, union, vacuum, sanitary, O-ring,
BSP. metric and DIN
Industry Approvals & Compliances
To industry standards
Pressure Rating
Pressure range
3250 psig to 185 psig operating pressure, depending on inside diameter and operating temperature (see Temperature Correction Chart below). Operating pressures based on 4:1 safety factor; operating pressure x 4 = rated minimum burst pressure at 70ºF (21ºC).
Product Designation Codes
MDS6 - 316 stainless steel double braid
MSS6 - 316 stainless steel
MSS4 - 304 stainless steel
CF16 - 316 stainless steel
CF04 - 304 stainless steel
All braid reinforcement is 304 stainless steel.
Consult factory for availability of larger sizes and inner cores of other alloys.
Metal hose is rated for full vacuum.
Specifying the Proper Metal Hose
A number of factors should be taken into consideration when specifying 316L/304 Stainless Steel Metal Hose.
Material to be transferred
Select 316L or 304 stainless steel inner core, depending on the type of medium.
Corrosion potential
The corrosive nature of both the medium to be conveyed and the outside environment should be taken into account; the corrosive effects of many chemicals can be accelerated by higher temperatures.
If the material to be transferred is gaseous, flow rates should be specified, especially if velocity is to approach or exceed 180 feet per second.
Are the fittings to be of the same material?
Inside diameter (ID) of hose
Relationship of pressure rating, temperature and type of service
Operating pressures listed in the accompanying specifications chart (above) reflect a rating based on one braid reinforcement and a minimum safety ratio of 4:1. burst pressure to rated operation pressure.
Ratings are based on operating at ambient temperature 70ºF (21ºC). If your application exceeds this temperature, consult the temperature correction chart to calculate the adjusted pressure rating at your particular operation temperature.
Maximum service temperature
316L stainless steel: +1500ºF (+815ºC)
304 stainless steel: +850ºF (+454ºC)
