Designed for assemblies that require smooth rotation and dependable connection performance, the a10-1772-05l swivel union helps reduce hose stress, simplify installation, and support consistent fluid or air transfer in compatible systems. Whether you are replacing a worn component, building a new assembly, or sourcing a dependable spare, this swivel union is intended to provide a practical connection point where movement, alignment, and durability matter.

Built for practical performance

A swivel union is a small component with an important job: it allows connected lines or fittings to rotate without forcing the entire assembly to twist. The result is cleaner routing, reduced strain, and easier maintenance access in tight or active equipment layouts.

The a10-1772-05l swivel union is a strong choice for buyers who need a replacement part identified by this specific model number and want a straightforward sourcing experience.

Key benefits

• Helps reduce hose and fitting stress by allowing rotational movement at the connection point.
• Supports easier installation when alignment is difficult or space is limited.
• Useful for maintenance and replacement needs where the A10-1772-05L part reference is required.
• Designed for compatible industrial, mechanical, or fluid-handling assemblies where swivel action can improve connection flexibility.
• Helps minimize downtime by making it easier to replace the correct part when specifications are verified before ordering.

Product features

• Swivel union design for rotational connection flexibility
• Intended for use with compatible fittings, hoses, or system components
• Suitable for replacement, repair, or assembly applications requiring this part number
• Compact connection component for equipment layouts where movement or alignment is a concern
• Practical solution for procurement teams, maintenance departments, technicians, and equipment builders

H-type rotary joint, also known as cooling water rotary joint, is a series of products specially designed for cooling. It has the characteristics of small volume, light weight, and small friction torque. It adopts flat sealing technology, and the friction group selects different pairs of impregnated graphite, bronze, tungsten carbide, and silicon nitride materials according to the medium environment, which can resist the influence of impurities such as rust, scale, and debris on the sealing surface. Our seals are completed on CNC machine tools and special grinding machines, with a mirror like surface, making the sealing more reliable. At the same time, high-precision rolling bearings are also used to ensure smooth rotation.

The H-type rotary joint is named after its shell structure, where H refers to a copper shell structure. As H-type rotary joints are mostly copper shells, they are referred to as H-type rotary joints. According to the circulation mode, it can be divided into HD type unidirectional circulation rotary joint and HS type bidirectional circulation rotary joint. HS type bidirectional flow rotary joints are divided into HS-G type bidirectional flow fixed internal pipe rotary joints and HS-X type bidirectional flow internal pipe rotary joints according to the installation form of the inner pipe. If the outer pipe of the rotary joint is connected to the equipment shaft neck using a flange connection, add the suffix F, such as HS-XF40-20, HS-GF40-20, where 40mm refers to the nominal flow diameter of the outer pipe of the rotary joint being 40mm, and 20mm refers to the nominal flow diameter of the inner pipe of the rotary joint being 20mm. The outer pipe of the rotary joint is connected to the equipment shaft neck using a threaded connection without adding a suffix, such as HS-X40-20, HS-G40-20, but the rotation direction of the outer pipe of the rotary joint should be opposite to that of the equipment drum. In this way, Spinning tighter and tighter. ）
