\"BSP<\/figure>\r\n\r\n\r\n\r\n

The AB adapter is a BSP male tee with three male stud ends, each machined with a 60 degree cone seat. One port takes the supply and the two remaining ports send the flow onward, so a single pressure line can feed two branches without adding a separate manifold block. Because every end is a male stud end with a metal-to-metal cone seat, the AB adapter is installed into female ports that already carry the matching 60 degree cone.<\/p>\r\n\r\n\r\n\r\n

Choosing the right tee is not only a question of thread size. The branch port often differs from the two run ports, and the way flow splits between the two outlets changes the pressure available at each branch. This page covers the configuration logic, the complete dimension table, the sealing principle, installation practice and the questions buyers ask most often.<\/p>\r\n\r\n\r\n\r\n

1. What the AB Adapter Does<\/h2>\r\n\r\n\r\n\r\n

A tee is a three-port fitting. In a hydraulic circuit it does one of three jobs: it divides one supply into two consumers, it combines two return lines into one, or it provides a take-off point for a pressure gauge, a pressure switch or a test point. This tee performs all three roles with male stud ends, which means the ports it screws into must be female ports with a 60 degree cone seat.<\/p>\r\n\r\n\r\n\r\n

The sealing principle is identical on all three ports. The 60 degree cone on the adapter nose is pressed against the matching cone in the female port, and the two metal cones deform slightly at the contact band to form a seal. No bonded washer, no O-ring and no thread sealant is needed on a correctly machined 60 degree seat, provided the torque is correct and both cones are clean and undamaged. The cone angle and the surface finish of the cone therefore matter as much as the thread designation.<\/p>\r\n\r\n\r\n\r\n

Because a tee is a single body, the branch flow passes through an internal intersection. That intersection is the point of highest local velocity in the fitting. When one branch is much smaller than the run, most of the flow is forced through a short reduced section and the pressure drop across the tee rises. Buyers sizing a tee for a high-flow line should therefore check the branch bore, not only the thread size.<\/p>\r\n\r\n\r\n\r\n

2. AB Adapter Specifications<\/h2>\r\n\r\n\r\n\r\n

2.1 Product Scope and Configuration<\/h3>\r\n\r\n\r\n\r\n

The range covers equal tees, where all three ports share one thread size, and reducing tees, where the branch port differs from the two run ports. In the reducing part numbers the first and third numbers are the run ports and the middle number is the branch port, so the three-port layout is symmetrical about the branch. Both configurations use the same body style and the same 60 degree cone seat on every end.<\/p>\r\n\r\n\r\n\r\n

2.2 Materials and Surface Treatment<\/h3>\r\n\r\n\r\n\r\n

Standard supply is carbon steel with zinc plating for general hydraulic service. Where the fluid, the wash-down regime or the outdoor environment is aggressive, 304 stainless steel or 316 stainless steel is used instead, and brass remains available for lower-pressure industrial and instrument lines. Plating options include trivalent chromium zinc (Cr3+) and zinc-nickel for a higher corrosion demand. No salt-spray hours and no plating thickness figures are published on this page; the current test report should be requested from the supplier before a specification is frozen.<\/p>\r\n\r\n\r\n\r\n

2.3 Threads, Standards and Sealing Principle<\/h3>\r\n\r\n\r\n\r\n

The three thread columns in the table are labelled E, F and G. E and G are the two run ports and F is the branch port. All threads are BSP parallel threads to ISO 228-1, and the seal is made by the 60 degree cone seat rather than by the thread, so the thread itself does not need a sealant. This is the classic BSP 60 degree seat interface used across hydraulic power units, and it should not be confused with a taper thread joint, which seals on the thread flanks.<\/p>\r\n\r\n\r\n\r\n

2.4 Dimensions and Part Numbers<\/h3>\r\n\r\n\r\n\r\n

All dimensions are in millimetres. A and C are the two run-port lengths (ports E and G), B is the branch-port length (port F), and S1 is the across-flats size of the body. On an equal tee A, B and C are identical; on a reducing tee the branch dimension B changes with the branch thread size.<\/p>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n

2.5 Working Conditions and Limits<\/h3>\r\n\r\n\r\n\r\n

The usable working pressure of any 60 degree seat fitting depends on the thread size, the body material and the strength of the female port it is screwed into, so no single figure covers the whole range. For a specific project, state the fluid, the working pressure, the peak pressure, the temperature range and the vibration environment, and the supplier will confirm the appropriate material, plating and torque values. Carbon steel with zinc plating suits general mineral-oil hydraulic service; stainless steel is the usual answer where the fluid or the atmosphere is corrosive.<\/p>\r\n\r\n\r\n\r\n

3. Part Number Decoding<\/h2>\r\n\r\n\r\n\r\n

The part number is built from the port sizes, written in the same order as the thread columns E, F and G.<\/p>\r\n\r\n\r\n\r\n
