Oil Connectors, Hoses & Oil Line Fittings

Oil line fittings, adapters, and hoses provide a leak-free seal and connection for different systems including oil, transmission fluid, power steering fluid, and others. This provides peace-of-mind and safety that your plumbing is sound and that there will not be any puddles under your vehicle.

Installing oil hose fittings with a finish that will compliment your vehicle or engine will provide that next level of detail to help turn heads and look nice at events and car shows. Choose from different colors of anodized aluminum such as red, blue, or black, as well as chrome plated steel or brass.

When replacing automatic transmission oil cooler connectors in the radiator, the first step is to remove the old connectors. Most can be removed with a flare nut line wrench. Next, measure the connector size for the threads that go into the radiator and the threads the transmission line uses. Then purchase the replacement fittings. Installation of the radiator oil line connectors is the reverse of removal.

When assembling low-pressure fuel hoses, standard fuel hose can be used with hose clamps and hose barb fittings. For oil and fuel hoses, where high pressure is present, Push-Loc hose and Push-Loc fittings or AN fittings and hose are required. Push-Loc hose assembles by simply pushing the end of the hose onto the fitting until it is all the way into the "cup". The design of the barbs on the fitting locks the hose in place with no clamps needed. For AN hose assemblies (used in many applications including oil tank fittings), the first step is to cut the hose to the length needed (with either a cut-off wheel, cable cutters, or a hacksaw with two opposing blades installed). Next, the fitting is taken apart by unscrewing it into two parts. The hose is pushed and twisted into the socket side of the fitting assembly until completely seated. Next, a vise jaw protector and vise helps to hold the installed fitting in place and protect it from scratching. The hose barb part of the fitting assembly is next pushed into the hose with the help of hose assembly oil and started on the threads of the socket side of the assembly by hand. Next, an AN wrench is used to tighten the two fittings together. Note that when tightening, do not completely draw the fitting pieces tight, just to within 1/16 of an inch to prevent them from galvanizing and to maximize clamping force. Assemble the fitting on the other end of the hose to complete the hose assembly. The hose can then be installed in the vehicle with the appropriate adapters. When repairing or connecting two hard lines, compression fittings for oil lines can be used. These are used by first disassembling the fitting. Next, slide the female coupler component of the compression fitting onto the line and then the included ferule or "olive". Next, the male end of the compression fitting is set up on the end of the line and is hand-tightened to draw the three components together on the end of the line. Wrenches are used to tighten the fitting, which squishes the ferrule/olive to create a seal. An additional compression fitting can be used on the end of the other joining line (if applicable) and the two can be connected together with a union. Quick disconnect fittings can also be used, assembled by a connection at a break in an oil or transmission cooler line.
