Quick acting couplers

Legris remains responsive to specific market needs with an enhanced range of stainless quick acting couplers.

What is the purpose of a Quick Acting Coupler ?

Quick acting couplers enable frequent rapid connection and disconnection without the use of tools or specialist equipment. They enable easy maintenance of a circuit or replacement of a component or tooling, avoiding the shut-down of a machine or production process.

Legris couplers are available with single or double shut-off operation. The latter is designed to prevent leakage of dangerous or toxic fluids.

Constituent materials

Legris quick acting couplers are manufactured from stainless steel AISI 316L: body, ring, balls and probes. Springs are stainless steel AISI 316 Ti.

As standard, seals are FKM, providing high resistance to acids, hot water, oils and many aggressive fluids.

●Application fields

Stainless steel AISI 316L is compatible with many fluids, and thus

numerous applications:

●food industry: e.g. supply of CO2, water, gas or organic acids

●chemicals: e.g. supply of CO2, water, gas or organic acids

●medical and pharmaceuticals: for filtration systems or analysis equipment

●industrial equipment: cooling circuits for injection moulds or presses

●construction: conveyance of compressed air, oils or water

for general use where aggressive washdown chemicals are inregular use.

Legris couplers are available with single or double shut-off operation. The latter is designed to prevent leakage of dangerous or toxic fluids.

●The Legris range

Legris AISI 316L stainless steel couplers are suitable for aggressive environments and fluids. X20 and X21 are compact series. X25 and X27 series are perfectly suited for

applications requiring higher flow due to their large diameter passage.
