Quick-Connect Coupling With Barbed Tailpiece for 12mm Hose, Brass

Brief Overview

This brass quick-connect coupling with integral barbed tailpiece is engineered for reliable, repeatable connections in pneumatic systems and fluid transfer applications. The 12mm hose interface makes this ideal for mid-range compressed air and fluid line work. The polished brass construction ensures corrosion resistance and longevity in workshop and industrial environments. If your operation requires multiple hose sizes, consider complementary options like smaller 8mm quick couplings or larger 1/2-inch quick connectors to create a complete coupling ecosystem for your shop.

Key Features

• Integral Barbed Tailpiece: Multi-step hose barb design ensures secure, leak-free connections to 12mm hose without additional clamps
• Brass Construction: Naturally corrosion-resistant; maintains performance in humid workshop conditions and repeated use cycles
• Quick-Release Sleeve: Two circumferential grooves enable fast disconnect with minimal fluid spillage
• Hexagonal Wrench Section: Integrated wrench flat allows positive hand-tightening or wrench engagement for secure installation
• Internal Valve Design: Built-in check valve visible in the bore prevents backflow and maintains system integrity during disconnection
• Polished Finish: Professional appearance with durable surface treatment resistant to oxidation

Business Advantages for Resellers

• High-Margin Accessory: Quick couplings command consistent markup; low per-unit cost with strong customer demand
• Bulk-Order Ready: Ideal for fleet shops, service centers, and pneumatic tool distributors restocking essential connection hardware
• Repeat Business Driver: Shops regularly purchase replacement couplings as maintenance or upgrade inventory—establish this as a stock item
• Versatile Application Base: Suitable for air lines, water cooling systems, and light hydraulic circuits—widens your customer base
• Complete Range Opportunity: Stock multiple hose sizes (6mm through 1/2-inch) to position your operation as a one-stop coupling supplier
