Quick Connect Coupling with 3/8" Female Thread, Nickel-Plated Brass

Brief Overview

This 3/8" female threaded quick-connect coupling provides a dependable, sealed connection point for pneumatic lines, air tools, and fluid transfer systems. The nickel-plated brass construction resists corrosion and ensures long service life in shop and field environments. Whether you're building tool kits or stocking repair inventory, this coupling integrates seamlessly with standard 3/8" threaded connections. For comprehensive system options, consider pairing this with [male-threaded quick connectors](https://place-holder-link/{ID: 1479}) and [1/4-inch alternatives](https://place-holder-link/{ID: 43}) for flexible application coverage.

Key Features

• 3/8" Female NPT Thread: Direct integration with standard male-threaded hose barbs, adapters, and pneumatic components
• Nickel-Plated Brass Body: Corrosion-resistant finish suitable for workshop, mobile, and outdoor use
• Sealed Quick-Connect Socket: Internal O-ring seal prevents air/fluid leakage during connection and disconnection
• Knurled Grip Collar: Textured mid-body sleeve provides secure hand control for one-handed coupling and uncoupling
• Hexagonal Wrench Flats: Integrated wrench flats enable torque-tight installation without slipping
• Precision Internal Threads: Machine-cut female threads ensure consistent, leak-free mating with male connectors

Why Resellers Choose This Coupling

Stock Efficiency: 3/8" is the most common pneumatic system size—stocking this configuration captures the widest range of repair and assembly jobs across automotive, fabrication, and general workshop operations.

Margin Security: Durable brass construction means minimal returns and warranty issues. Customers buy once and rely on the coupling for years, supporting repeat business for your other consumables and upgrades.

System Compatibility: The female thread design complements male adapters and hose connectors already in most shop inventories, reducing customer friction and supporting bundled sales.

Professional Presentation: Nickel plating and precise manufacturing convey quality—customers perceive this as a premium, reliable product worth the margin.

Why This Specification Matters

The 3/8" female thread is the industry standard for mid-range pneumatic systems. Unlike smaller 1/4" couplings (suitable for low-flow applications), the 3/8" bore minimizes pressure drop in active shop environments. The female thread design provides a clean, compact integration point—ideal for hose assemblies, manifolds, and tool connections. The quick-connect socket eliminates the need for separate male plugs, reducing inventory complexity and assembly labor.

The nickel-plated brass body strikes the professional balance: it's robust enough for daily shop use, corrosion-resistant enough for humid or mobile environments, and cost-effective enough to stock in quantity without significant capital tied up.

Call to Value

Stock this coupling as a foundational pneumatic component. It pairs with hoses, adapters, and male connectors to create complete system solutions that your customers depend on. At this price point and durability level, it's a high-confidence item that supports margin while building customer loyalty through reliability.
