Hol­ley has an­nounced the re­lease of the UltraPro se­ries of hose and fit­tings from Earl’s Per­for­mance Plumb­ing. The UltraPro Se­ries hose fea­tures a car­bon-in­fused PTFE in­ner liner that is im­per­vi­ous to all known fu­els, oils, and coolants used in au­to­mo­tive ap­pli­ca­tions while main­tain­ing an ul­tra-low co­ef­fi­cient of fric­tion to pro­mote max­i­mum flow. The dou­ble­he­lix ribbed in­ner hose liner of­fers ex­treme flex­i­bil­ity and full flow mak­ing tough plumb­ing jobs a snap with less hard con­nec­tions. The liner is re­in­forced with an out­side glass-fiber wrap for ad­di­tional strength and in­tegrity. It is avail­able in -6, -8, -10, -12, -16, and -20 AN sizes. The polyester braid UltraPro hose is up to 67% lighter than tra­di­tional rub­ber hose with stain­less steel braid while the stain­less braid UltraPro hose is up to 37% lighter than tra­di­tional steel-braided rub­ber hose.

Earl’s UltraPro Se­ries hose ends are de­signed to stand up to the same harsh en­vi­ron­ments. In­ter­nal seals are a flu­o­roe­las­tomer ma­te­rial, which is re­sis­tant to all known fuel, oil, and coolants. The hose ends are fur­nace-brazed for a per­ma­nent and ro­bust bond. They are as­sem­bled with an olive that threads onto the dou­ble-helix ribbed in­ner liner of the hose for pos­i­tive en­gage­ment and re­ten­tion of the hose ends. High-stress com­po­nents are made of high strength 2024-T8 grade alu­minum. The de­sign of the nuts, sock­ets, and swivels has been op­ti­mized for max­i­mum weight sav­ings. They also fea­ture Earl’s pop­u­lar ANO-TUFF black hard-coat an­odiz­ing that ac­tu­ally pen­e­trates the alu­minum for an ex­traor­di­nar­ily durable and cor­ro­sion-re­sis­tant shield. Dy­namic Swivel tech­nol­ogy is used in se­lected hose ends which al­lows 360° of ro­ta­tion af­ter in­stal­la­tion. They are avail­able in both twist-on and crimp-on styles for more plumb­ing op­tions. SAE port, jump size, and Wig­gins con­nec­tor adapters are also avail­able.
