TR Series Tru-Flate Type Quick Couplings

TR Series Tru-Flate Pneumatic Quick Couplings for Flexible Air Connections

TR Series Tru-Flate pneumatic quick couplings are designed for air lines that need convenient connection and disconnection during equipment setup, tool changes, or routine maintenance. The series follows the Tru-Flate interface design and is listed as interchangeable with Parker 10 Series nipples, helping users select compatible connection components for pneumatic systems. Before ordering, confirm the coupling profile and the exact mating part.

Key Features and Available Configurations

The TR series combines three body sizes with multiple connection styles, allowing the same coupling family to serve different hose and pipe arrangements.

● Three body sizes: TR20 (1/4"), TR30 (3/8"), and TR40 (1/2").

● Rated pressure: 2.0 MPa for all three sizes, according to the supplied specifications.

● Temperature range: -10°C to +70°C.

● Locking mechanism: 4 balls for TR20, 6 balls for TR30, and 8 balls for TR40.

● Socket options: Female pipe thread (SF), male pipe thread (SM), hose barb (SH), and hose-barb locking type (SHL).

● Plug options: Female pipe thread (PF), male pipe thread (PM), hose barb (PH), and hose-barb locking type (PHL).

The ordering code also identifies body size, coupling type, thread code, and material. Available material codes shown in the product information include brass, carbon steel, and stainless steel (SUS304/303). Select the material and connection combination according to the working medium and installation requirements.

Where TR Series Quick Connect Couplings Are Used

TR Series pneumatic quick couplings are suitable for compressed-air connections in industrial automation equipment, pneumatic tools, air supply lines, and machinery requiring frequent connection changes. The choice of body size should reflect the required airflow and the dimensions of the connected line. Check the complete system pressure and medium compatibility before use.

Installation and Connection Checks

Choose a matching socket and plug, then verify the body size, thread standard, and hose inner diameter. Secure threaded connections with a suitable sealing method and fasten hose connections correctly. Before operation, inspect the connection for leakage and confirm that the coupling locks securely. Disconnect the air supply and release residual pressure before servicing or changing components.
