Flexible Hoses
Mason Industries
MN Series
Our steam service ratings are very low in the interest of safety although our 70°F (21°C) pressure ratings are as high or higher then our competitors. All locations where failure could lead to personal injury or suffocation must be avoided. In dangerous locations we suggest housed expansion joints, solid loops, ball joints, packed devices, etc. rather than thin-walled flexible products regardless of manufacturer.
Consult factory with full location description as well as service conditions for higher pressure or temperature applications.
304 SS can be used up to 850°F (454°C) in applications such as engine exhaust.
When using these products in copper or brass water or steam systems, dielectric couplings must be used on each end to prevent leakage from galvanic action.

FFL Series
FFL Braided Stainless Steel Hose has fixed and floating raised face flanges. Years ago, almost all stainless steel hose was manufactured with a floating flange on one end. It is still important because it makes lining up the holes easier during installation, and eliminates the possibility of twisting the hose, when the holes do not line up. Twisting contributes to early failure.
Raised face flanges seal better. Most competitive plate flanges have flat faces to reduce machining costs, but the raised face is the better product as sealing pressure increases by factors of 2 & 3 because of the reduced gasket area.
All of our stocked flanged hoses have one floating flange.

CSA Series
Everyone is concerned when installing flexible hose in flammable gas or liquid lines because of the risk of both asphyxiation and fire. Approved by the CSA, the successor to the American Gas Association, and complying with UL 536 provides that assurance. Tests include vibration 300 hours at 15 Hz, 90° bends at rated pressure @ 10 cpm for 20,000 cycles, elongation and tension, 450°F (232°C) for 100 hours as well as flame resistance. All of our standard hoses 1/2″ through 4″ diameter passed and can be used in straight, looped or Vee configurations. However, in addition to the general UL approval, all specific hoses must be rechecked with an approved thread gauge, if threaded, and retested to 50% above rated pressure using water or rated pressure using air. It must be clearly identified as a Mason product and tagged with maximum pressure rating and minimum bend radius.

RFFL Series
Our steam service ratings are very low in the interest of safety although our 70°F (21°C) pressure ratings are as high, or higher, than our competitors. All locations where failure could lead to personal injury or suffocation must be avoided. In dangerous locations we suggest housed expansion joints, solid loops, ball joints, packed devices, etc. rather than thin-walled flexible products regardless of manufacturer.
Consult factory with full location description as well as service conditions for higher pressure or temperature applications.
304 SS can be used up to 850°F (454°C) in applications such as engine exhaust with minor pressure.
When using these products in copper or brass water or steam systems, dielectric flanges and/or couplings must be used on each end to prevent leakage from galvanic action.

CPSB Series
All Services Except Refrigerant
Copper Lines have virtually no stiffness or mass. We are recommending our longest standard lengths primarily for offset, not vibration reduction.
Consult factory with full location description as well as service conditions for higher pressure or temperature applications.
Not suitable for steam.

ULCPS Series
Approved for Refrigerant Services
U.L. approved flexible hose are cleaned and bagged for refrigeration service. Do not use for water service.
