Quick Connector with Internal Thread, 1/4-Inch for 5/16-Inch Hose

Brief Overview

This brass quick connector delivers reliable inline connection for pneumatic and fluid systems requiring a 1/4-inch threaded port and 5/16-inch hose compatibility. The internally threaded design allows direct integration into manifolds, regulators, and compressed air equipment without adapter fittings. The barbed hose tail ensures positive retention and eliminates the need for hose clamps in most applications. Available as part of a complete range including larger 1/2-inch threaded quick connectors and alternative hose sizes like the 3/8-inch variant for system flexibility.

Key Features

• Internal Thread Design: 1/4-inch threaded bore for direct port connection
• Barbed Hose Tail: Three-ridge barb system locks 5/16-inch hose securely without clamps
• Brass Construction: Yellow-brass material with zinc-chrome plating for corrosion resistance
• Hex Wrench Flat: Hexagonal nut body accommodates standard wrenches for installation and removal
• Compact Form Factor: Stepped shank minimizes space requirements in tight equipment layouts
• Smooth Machined Finish: Professional appearance with clean surface quality

Business Advantages for Distributors

• High-Velocity SKU: Quick connectors are essential components in every pneumatic shop's inventory—predictable demand ensures consistent turnover
• Margin-Friendly: Compact size and low material cost translate to excellent unit economics
• System Compatibility: Stock this size alongside 1/2-inch port variants to capture multiple application categories (air tools, paint systems, automation)
• Installation Labor Savings: Barbed design reduces labor overhead for end-users, increasing perceived value
• Cross-Sell Opportunity: Customers ordering this connector often need multiple sizes—position alongside larger and smaller variants to increase basket value

Why This Connector Matters

The internal thread design eliminates the need for separate male-threaded adapters, reducing fitting count and potential leak points in compressed air systems. The barbed tail grips the hose wall mechanically, providing secure retention even under vibration or pressure fluctuation. This is the foundational component for equipment assembly, maintenance kits, and system upgrades.
