Select options This product has multiple variants. The options may be chosen on the product page / DetailsQuick coupling plug with shut-off valve Gromelle type MLDB with internal "flat-face" thread made of high-purity steel (VIM-VAR melting). Used, among others, in industrial installations where ideal cleanliness is required (nuclear, food, pharmaceutical industries, semiconductor production, perfumes). Not intended for connecting - disconnecting under pressure. Working pressure: 25 bar (safety factor 4:1). Operating temperature: from -20°C to +200°C (viton), from -40°C to +150°C (EPDM). Material: AISI 316L steel.- Select options This product has multiple variants. The options may be chosen on the product page / DetailsNitto Kohki series PCV PIPE CUPLA quick-connect fittings with external BSPT thread, designed for connecting copper tubes with other installation components. The connection is made by inserting the tube into the fitting and tightening the clamp; the double sealing ensures a leak-proof connection. Used for gas media (air, nitrogen, refrigerants - freon R12, R22, R134a along with compressor oil). Depending on the medium, the type of sealing must be selected. Applications include testing the tightness of tanks, draining and filling systems in air conditioners, refrigerators, etc. Material: brass. Working pressure: 45 bar (vacuum up to 0.13 Pa). Operating temperature: from -20°C to +80°C (chloroprene), from -20°C to +180°C (viton), from -20°C to +120°C (HNBR).

The options may be chosen on the product page / DetailsNitto Kohki series SP CUPLA type A socket with a shut-off valve and internal BSPT thread, featuring excellent durability, designed for water, hydraulic oils, steam, chemicals, air, and gases. Material: AISI 304 steel. Working pressure: 75 bar (1/8", 1/4", 3/8"), 45 bar (1/2", 3/4", 1"), 30 bar (1.1/4", 1.1/2"), 20 bar (2"). Operating temperature: from -20°C to +80°C (NBR), from -20°C to +180°C (Viton).
- Select options This product has multiple variants. The options may be chosen on the product page / DetailsCEJN NON DRIP quick coupling socket (leak-free) with valve, designed for fluid transfer (water, oil, chemicals, etc.). Flat contact surfaces minimize potential fluid leakage and prevent air inclusion while allowing for easy maintenance of the coupling's cleanliness. Sockets and plugs are available in versions with or without a shut-off valve, allowing for three coupling configurations: free flow, one-sided shut-off (socket must have a valve), and two-sided shut-off (leak-free). Protective caps are available to shield the coupling from contaminants when disconnected. To ensure additional safety, when interchangeability between socket and plug is not permissible, the coupling can be color-coded: green (standard) and optionally black, blue, red, white, and yellow, or key coding, where the socket and plug have additional grooves and protrusions, allowing only properly matched coupling connections. Material: nickel-plated brass. Sealing: NBR, Viton, EPDM. Working pressure: 20 bar. Operating temperature: from -15°C to +205°C, depending on the type of sealing.
