Key Features of the CPC PLC1600412
Durable Acetal Body with Chemical Resistance
The coupling body is molded from Acetal (POM) engineering plastic – a high-performance material offering excellent rigidity, dimensional stability, and resistance to most mild chemicals, solvents, and clean water. Its mechanical lifespan extends to tens of thousands of connect/disconnect cycles, far surpassing standard plastic fittings available on the market.
Automatic Shutoff Valve (Auto-Shutoff)
When the latch is pressed to disconnect, the internal valve closes immediately, preventing fluid or gas from escaping. No additional manual steps are needed – ideal for clean environments, expensive chemicals, or pressurized systems where spillage is unacceptable.
One-Hand Operation Latch
CPC’s proprietary stainless steel thumblatch enables full connection or disconnection with a single one-hand press, producing a firm audible “click” to confirm secure engagement. No wrenches, no threading – significantly reducing maintenance and operational time.
Panel Mount Design
The threaded outer body with a metal hex nut allows easy mounting through control cabinet walls, machine panels, or technical brackets – ensuring a clean, professional installation with a secure hold.

Frequently Asked Questions (FAQ)
What inner diameter tubing is compatible with the 1/4″ barb on the PLC1600412?
The 1/4″ Hose Barb is designed to fit snugly into flexible tubing (Silicone, Tygon, Polyurethane, soft PVC) with an inner diameter (I.D) of approximately 6.4 mm. For a secure, leak-free connection under pressure, use a hose clamp or choose tubing with a slightly smaller I.D (~5–6 mm) and stretch it over the barb.
Is the Acetal body and Buna-N O-ring FDA-compliant for food contact?
The standard PLC Series materials meet general industrial cleanliness requirements, but are not certified to FDA/NSF standards for direct food contact. If your application requires FDA compliance, please contact NTN Technology for guidance on switching to Polypropylene body material or a CPC food-grade model.
How does the valve function when mated with a Non-Valved Insert?
When connected, the insert pushes open the valve inside the PLC1600412 socket, allowing fluid to flow freely through both sides. Upon disconnection, only the socket side (PLC1600412) automatically closes its valve; the non-valved insert side remains open. To shut off flow from both sides upon disconnection, pair this socket with a Valved Insert.
