Dixon, TGL64, 4' Long Style Carbon Steel External Swage Stem with Grooved EndFeaturesTubular typeThe coupling system requires no bolts and results in a clean coupling with no protrusionsThe Holedall coupling provides long-lasting efficiency and safetyApplicationsRecommended for use where additional retention is required due to higher working pressures or end pull, on most one and two wire braid reinforced hoses, fiber reinforced (braided or spiraled) with or without helical wire such as: oil and suction discharge hose, barge and dock loading and unloading hose as well as L.P. gas hose, anhydrous ammonia hose, acid chemical hose and air and water hoseUseDesigned for hose ID's 1-1/4"" - 10". The ferrule size depends on the hose ODSafety notesDixon Holedall stems and ferrules are specifically designed to be used together as a coupling system.Due to differences in dimensions and tolerances, for safety reasons, do not use other manufacturer's stems or ferrules with Dixon Holedall products.Do not use a wrench or vice on ferruleHoledall couplings, regardless of coupling style, are never to be used for steam service at any pressure.Holedall fittings are not to be used with cable reinforced high-pressure hose, 4 or 6 braid wire hydraulic hose or any other service not listed in the recommendations. Externally swaged Holedall couplings, to perform satisfactorily, must be applied properly in accordance with Dixon's assembly procedures, using correct die and ferrule for that particular hose end OD. Hose service working pressure (including surges and spikes) is never to exceed the maximum recommended working pressure for the fitting. The assembly's (hose + coupling) maximum working pressure is the lesser of the hose rated working pressure or the coupling rated working pressure.Media being transported through the hose should be compatible with the stem material. Compatibility of ferrule material with the environment in which it will be used is recommended.
