  • FDM (V): -20°C to +180°C
  • EPDM (Ethylene Propylene): -40°C to +150°C
• Working Pressure: Up to 35 Bar (510 PSI)
• Flow Size: Nominal diameter 19 mm (DN 19)
• Materials:
  • Balls and Springs: Stainless Steel (316L or 303 depending on option)
  • Socket Body, Sleeve, Plug, Nipple: Brass
  • Seals: Nitrile standard
• Features: High flow rate, minimal pressure loss, corrosion resistant, one-hand operation

Interchangeability

The T039 Series is interchangeable with other common coupling brands such as Cejn 408, Rectus 39KB, Tema 1800, and Rectus 39KA, facilitating easy replacement and compatibility.

Flow Rate and Pressure Drop

Graphs indicate the relationship between flow rate (L/min) and pressure drop (bar) for air and water. The couplings maintain low pressure loss even at high flow rates, ensuring efficient fluid transfer.

Product Variants and Ordering Information

The series includes multiple variants differentiated by connection types, valve options, and sizes:

• Connection Types: Male thread, female thread, standard hose tail socket, standard hose tail plug
• Valve Options: With valve, without valve, double valve
• Thread Sizes: BSP 1/2, BSP 3/4, BSP 1, BSP 1-1/4
• Dimensions: Detailed dimensions (ØD1, ØD2, L1, L2, Hex) are provided for each variant to assist in selection and installation.

Material and Construction Details

The standard version uses brass for the main body components and stainless steel for internal parts like balls and springs, ensuring durability and corrosion resistance. Seals are typically nitrile but can vary based on temperature requirements.

Key Advantages

• High flow capacity reduces operational delays
• One-hand operation improves usability and safety
• Corrosion resistance extends service life
• Wide temperature range accommodates diverse applications

Recommendations and Best Practices

• Select seal material based on operating temperature to ensure longevity
• Verify compatibility with existing coupling systems for interchangeability
• Use appropriate valve options depending on system requirements
• Consult dimensional data carefully to ensure proper fit and function
