Couplers, One-Touch Joints（Male/Female：Plug (Male) Page8）

We handle a number of couplers and one-touch joints. By using the plug and socket as a set, it can be attached and detached easily. In the MISUMI e-catalog, you can select male and female types, volute type that can be used to mount tubes, nut tightening type and the like with one click, making it easy to find the desired coupler and one-touch joint.

[What is a coupler?]
It is a device that enables easy attachment/detachment by using a plug and socket in a set. It is selected from fluid temperature and type, pressure, availability of automatic opening/closing valve mechanism and mounting size shape. There are those with backflow prevention function for when removing the coupler and those without (no-bulb type).

S Coupler KK Series, Plug (P) Male Thread Type

SMC

S Coupler KK Series plug.
[Features]
・ Male thread type
・ The pulling strength of plug and socket improved by twice (Conventional ratio)
・ Effective cross-sectional area: 3.8 to 82 mm2
・ It is standardized with sleeve cover. Furthermore, the impact resistance is improved by changing the lock ring to impact resistant PBT
・ Since the structure does not use steel balls, it has a slim body without narrowing the flow path and has a large effective cross-sectional area
・ Structure with no spring installed in the flow path
・ Since the flow path is not blocked by the valve spring, the loss of effective cross-sectional area can be reduced
・ Check valve tip shape considering rectification effect
・ It enables smooth flow of fluid
・ Structure with little leakage
・ Surface contact ensures reliable sealing
・ It achieves a thorough weight reduction by adopting pressed parts and resin parts as well as downsizing the body
・ It standardizes quick-connect fitting type
・ It can be flown from either the plug side or the socket side
・ Sleeve lock mechanism prevents accidents due to unexpected detachment
