Asymmetrical BBA tees

We supply tees with side nuts commonly called asymmetrical. A BBA tee is a tee with two external threads and a swivel nut on the side. The version with a nut reduces the need for another fitting to connect two external threads. Metric asymmetrical tees 2 x external thread with a 24-degree cone seat, asymmetrical swivel nut secured with wire, 24-degree cone seal + O-RING. Our range includes BBA tees with metric, inch, UNF, and ORFS threads. Example of markings used: B = external thread, A= nut (internal thread).

Construction of BBA tees

BBA tees play a key role in hydraulics, enabling efficient branching of medium flow in pressure systems. Thanks to their design with two external threads and a swivel nut, they provide fast and leak-proof connections without the need for additional adapters. Their precise workmanship and cone sealing method guarantee reliability and durability in demanding operating conditions.

Application of adjustable tees

Tees are most often used for branching hydraulic systems or to tap into a system, e.g., to install a pressure gauge or other component. Tees are used in practically every branch of industry: agriculture, construction machinery, forestry machinery, and others. We also offer tees in versions: tee with external threads (BBB), symmetrical tees with center nut (BAB), tee with three nuts AAA as well as less popular types of tees such as: BAA, ABA, 

Available versions of BBA tees with threads:

• asymmetrical tees with metric threads

Hydraulic tees with side nut

What are hydraulic tees with side nuts? Side nut tees, also known as asymmetrical tees, are key components used in power hydraulics for separating and connecting lines and installing additional components, such as pressure gauges. They are characterized by the presence of two external threads and a swivel nut, which allows for a quick and leak-proof connection without the need for additional adapters. The best hydraulic tees with side nuts are made of high-quality free-cutting steel, often galvanized to increase corrosion resistance. A key aspect of the construction is the precision-made thread and the "cone" sealing method, which ensures maximum tightness of the connection without the need for additional seals.

Application of tees in power hydraulics

Side nut tees are widely used in hydraulic systems where high strength and pressure resistance are required. They are used, among others, in: ✔ Industrial hydraulic systems – for separating and connecting working fluid flows. ✔ Vehicle mechanics – in hydraulic control systems for construction and agricultural machinery. ✔ Shipbuilding and aerospace industries – in systems requiring precise and leak-proof connections. ✔ Agriculture, horticulture, and forestry – in hydraulic supply systems for machines and devices.

BBA tees in power hydraulic systems offer significant benefits, including increased efficiency through optimal flow separation. Their robust design ensures safety and durability, which is crucial in industrial and mobile applications. Additionally, the ease of installation and a wide range of sizes allow for flexible adaptation to various hydraulic systems.

BBA tee - thread variants and sizes

Our offer includes BBA tees in a wide range of sizes and threads, both metric (M16, M18, M20, M22, M26) and inch (7/8", 3/4", 1/2"). We also offer versions with different diameters for individual ports, allowing them to be adapted to almost any installation.
