Brass Quick Connector with Internal 3/8-Inch Thread for 1/2-Inch Hose

Brief Overview

This brass quick connector combines a threaded inlet with a barbed hose tail, providing a direct, no-leak solution for joining 1/2-inch hose to 3/8-inch internally threaded ports. The barbed design locks the hose firmly in place, while the hexagonal nut body ensures secure wrench grip during installation. As a distributor, you'll find this connector essential for assembling pneumatic, hydraulic, and fluid delivery systems. For complete system solutions, consider pairing this with alternative thread-size quick connectors that match different port configurations.

Key Features

• Barbed Hose Tail: Three concentric barbs grip 1/2-inch hose securely, preventing accidental disconnection under pressure
• Internal 3/8-Inch Thread: Female thread allows direct connection to 3/8-inch ports without adapters
• Hexagonal Brass Body: Provides wrench grip points (typically 13 or 14mm across flats) for tight installation and removal
• Machined Brass Construction: Yellow-brass finish resists corrosion and withstands moderate pressure environments
• Compact Design: Minimal footprint reduces assembly clutter and simplifies system layouts

Business Advantages for Resellers

• High Turnover Item: Quick connectors are consumable-adjacent components with consistent replacement demand across automotive shops, pneumatic tool assemblies, and agricultural equipment
• Margin-Friendly: Brass fittings carry strong wholesale margins due to material cost stability and straightforward manufacturing
• System Bundle Potential: Stock multiple thread and hose sizes to offer complete connector kits—customers often buy in sets
• Universal Application: Used in air lines, coolant systems, hydraulic assemblies, and generic fluid delivery—broad customer base
• Bulk Order Ready: Minimum order quantities typically unlock aggressive pricing; high-volume distributors see 35–45% margins

Installation & Maintenance

Thread the connector into a 3/8-inch internal port hand-tight, then secure with a wrench on the hexagonal body. Slide the 1/2-inch hose over the barbed tail until it seats fully against the shoulder—the barbs will resist pull-off under normal operating pressure. For hose removal, cut or carefully peel the hose away from the barbs; barb deterioration may occur after multiple connect-disconnect cycles in high-vibration environments.

Why This Connector?

The barbed design eliminates the need for hose clamps in moderate-pressure applications, reducing assembly time and part counts. The internal thread accommodates most standard port configurations, making this a flexible solution for system integrators and equipment manufacturers. Stock depth in this size pays dividends—it's the connector your customers ask for by default when building custom pneumatic and fluid systems.
