Industrial L-shaped pneumatic connector featuring an R1/4 male thread to 12mm port. Handles -0.95 to 14 bar pressure with a robust PBT body and NBR seal.
The Festo QSL-1/4-12 (Part Number 164981) is a professional-grade push-in L-fitting designed for efficient pneumatic routing in automated and fluid control systems. Featuring a rugged polybutylene terephthalate (PBT) body and a nickel-plated brass R1/4 male threaded plug, this 90-degree angled connector provides a secure, leak-free transition from block manifolds to 12mm outer diameter pneumatic tubing. A factory-applied thread coating enables immediate installation without the need for external thread sealant tape. Utilizing a reliable push-pull mechanism with high-alloy stainless steel retaining claws and an NBR seal, the fitting seamlessly grips the tubing. It is engineered to perform across a versatile operating pressure spectrum, supporting deep vacuum applications at -0.95 bar up to heavy industrial pressures of 14 bar (temperature dependent), making it a highly adaptable component for dynamic robotics, packaging machinery, and tight-clearance control cabinets.

Integrates directly with pneumatic valve manifolds and actuators, utilizing the L-shape geometry to save critical space while the push-in connector ensures rapid assembly and disassembly of the 12mm lines on the factory floor.
Routing compressed air lines in tight 90-degree corners around moving packaging arms without kinking the rigid 12mm tubing.
The internal NBR seal and high-alloy stainless steel retaining claws grip the 12mm tubing securely under deep vacuum conditions, preventing system leakage during critical heavy-lifting maneuvers.
Securing an airtight mechanical tubing connection that can reliably support -0.95 bar deep vacuum during automated pick-and-place operations.
The factory-applied PTFE coating on the R1/4 thread allows immediate, leak-free installation directly into the control panel's pneumatic headers, heavily accelerating panel assembly and reducing human error.
Assembling compressed air distribution blocks efficiently and securely without the mess and time delay of manually applying thread sealant tape.
