Parker 230-6-4 Barbed Tube Female Elbow 1/4-18 Brass

Product Description

The PARKER 230-6-4 is a barbed tube female elbow fitting designed for low-pressure fluid and pneumatic tubing connections. It features a female-threaded inlet at a 1/4-18 thread size and a barbed outlet sized for 0.25-inch inside diameter tubing with a 3/8-inch outside diameter. The elbow configuration allows a directional change in the tubing run without additional adapters. Constructed from brass, this fitting provides corrosion resistance in water, light hydraulic, and compressed air service. Plumbers, HVAC technicians, and fluid-system installers working with barbed soft tubing use this fitting as a compact, reliable connection point in tight spaces.

This fitting is suited for residential and light commercial plumbing, HVAC auxiliary drain lines, pneumatic control tubing, and similar small-bore fluid-conveyance applications. The female elbow design connects threaded ports on equipment or manifolds to flexible tubing, making it a common component in condensate systems, water supply lines, and instrument tubing assemblies. Its compact brass construction fits well in panel-mounted or bulkhead installations where space is limited.

Key Features

• Female elbow configuration allows a 90-degree directional change at a threaded port
• 1/4-18 female thread for direct connection to standard NPT or pipe-thread ports
• Barbed outlet sized for 0.25-inch ID tubing for a secure push-on grip
• Brass construction resists corrosion in water and light pneumatic service
• Compact design suited for tight-space installations

Compatibility

Designed as an OEM-style replacement or service fitting for small-bore barbed tubing assemblies using 0.25-inch ID flexible tubing and 1/4-18 threaded ports.

Installation Notes

Installation is performed by plumbers or HVAC technicians. Shut off water or air supply and depressurize the line before removing or installing any fitting. Apply thread sealant or PTFE tape to the female threads per applicable IPC or IFGC guidelines before engaging the mating male port. Push tubing fully over the barb to the shoulder to ensure a leak-free connection; a hose clamp is recommended for higher-pressure or vibration-prone service.
