|Holedall couplings, regardless of coupling style, are never to be used for steam service at any pressure. Holedall fittings listed below are not to be used with cable reinforced high-pressure hose, 4 or 6 spiral wire hydraulic hose or any other service not listed in recommendations. Consult the Tampa Rubber Customer Service Department for recommendations on usage.|
Holedall couplings, to perform satisfactorily, must be applied properly in accordance with our assembly procedures, using the correct die and ferrule for that particular hose end O.D. Our Die and Ferrule Recommendation Guide is to be used to select the correct dies and ferrules. If you do not have the updated Die and Ferrule Recommendation Guide, consult the Tampa Rubber Customer Service Department.
Note: Hose service working pressure (including spikes and surges) is never to exceed the maximum recommended working pressure for the fitting (reference the chart below)*. "King" safety cables are recommended for use whenever possible. Media being transported through the hose should be compatible with the stem material and ferrule material whenever possible. Consult the Tampa Rubber Customer Service Department for material compatibility. For applications other than the ones listed, please consult us.
Maximum recommended working pressures are in PSI, at 70ºF ambient temperature.

|* The assembly's (hose + coupling) maximum working pressure is the lesser of:|
1) The hose rated working pressure, or
2) The coupling rated working pressure.
** For hoses which use IXF-48-3 to IXF48-5 and IXF-64-2 to IXF64-5, consult the Tampa Rubber Customer Service Department for working pressures.
See notes below for specific recommendations.
Recommended for use on most one and two wire braid reinforced hoses, fiber braided and helical wire reinforced hose, such as oil suction and discharge hose, barge and dock loading and unloading hose, L.P. gas hose, anhydrous ammonia hose, aircraft fueling hose and acid chemical hose.
Long Style Fittings
Recommended for use on hose as listed under standard fittings where additional retention is required due to higher working pressures or end pull. Consult the maximum working chart or call the Tampa Rubber Customer Service Department.
Holedall II Fittings
Recommended for Royalflex P1193 and P1196 hose or hoses with similar construction, having a helical wire for a given O.D. range.
Light Duty Fittings
Recommended for use in the same applications as standard fittings above except that the hose rated working pressure is never to exceed the maximum recommended working pressure listed in the chart above.
