Description

Pneumatic Quick Connect Coupling Adaptor, Threaded Male 3/8-Inch, Brass

Brief Overview

This brass pneumatic quick-connect coupling adaptor bridges fixed pneumatic lines with portable equipment through a robust threaded male interface. The 3/8-inch thread sizing positions it as a standard interface for mid-range compressed air systems in automotive shops, industrial maintenance, and pneumatic tool stations. Whether you're building modular air distribution systems or need quick-swap capability for multiple tool configurations, this adaptor delivers the repeatability and reliability your operation demands. Stock it alongside female-threaded coupling adapters and smaller 1/4-inch variants to cover your full coupling inventory.

Key Features

  • Threaded Male Connection: 3/8-inch external threads for permanent installation on fixed air lines or manifolds
  • Quick-Connect Plug: Smooth cylindrical design with dual retention ridges for secure, leak-resistant mating with female sockets
  • Brass Construction: Corrosion-resistant, durable material suitable for continuous shop or industrial environments
  • Hex Wrench Flat: Integrated wrench-engagement surface simplifies installation and removal without risk of thread damage
  • Hollow Bore Design: Optimized internal geometry maintains full flow capacity across the adapter junction

Business Advantages for Resellers

Margin Driver: Quick-connect couplings are consumable-adjacent accessories—customers repurchase as systems expand or adapters wear. Brass construction extends lifecycle, reducing churn while maintaining demand.

Bundling Opportunity: Cross-sell with female couplers, hose assemblies, and pneumatic tool sets. This 3/8-inch size is a standard on mid-range impact wrenches and grinders.

Inventory Efficiency: Stock depth across multiple thread sizes (1/4", 3/8", 1/2") allows you to serve shops upgrading or standardizing systems without large SKU commitments per size.

Professional Credibility: Brass couplings signal quality to your customers—they're the choice of shops serious about system reliability, not cheap plastic alternatives.
