JoinTech quick-connect coupling with automatic shut-off – female x 13 mm hose barb | KL41102
JoinTech automatic shut-off quick disconnect (female) with 13 mm (1/2") hose barb – this is a professional quick-disconnect coupling for glycol systems, pumps, and fluid transfer. When not connected to another JoinTech coupling, the valve closes automatically and the fluid does not leak – no puddles on the floor, no lost glycol.
What is this quick disconnect for?
The KL41102 coupling is ideal for applications where hoses need to be frequently disconnected and connected without fluid leakage:
- Glycol cooling systems – cooling loops for fermenters, conical tanks, and kegerators
- Pump hoses – magnetic and diaphragm brewing pumps
- Hot liquid transfer – wort transfer, CIP cleaning loops
- Low-temperature systems – sub-zero glycol mixtures down to -40 °C
Key benefits
- Automatic shut-off valve – stops fluid flow on both sides when disconnected
- "Dry break" disconnection – lose only a few drops of liquid during disconnection
- Black UV-resistant housing – does not age or crack under light exposure
- Medical-grade materials – food and beverage safe
- Wide temperature range – from -40 °C to +138 °C
- One-handed operation – fast and convenient for handling equipment

Frequently asked questions
Does liquid spill when disconnecting?
No. The automatic valve closes the flow upon disconnection – only a few drops remaining in the coupling itself are lost.
Is it suitable for glycol and hot wort?
Yes. The temperature resistance from -40 °C to +138 °C allows for use with both cold glycol mixtures and hot liquid transfers.
What hose is suitable?
13 mm (1/2") inner diameter hose. We recommend securing it with a stainless steel hose clamp.
Do I need to buy both couplings?
Yes, for a functional assembly, you need both the female (KL41102) and male (KL41096) couplings.
