Parker NV105CA-6 Straight Needle Valve 3/8 in Compression

Product Description

The PARKER NV105CA-6 is a straight-pattern needle valve with compression-by-compression end connections and a brass body. It provides precise flow control in small-bore tubing systems and is rated for a maximum working pressure of 150 psi. The valve measures 1.78 inches overall length and 1.55 inches overall height, making it a compact solution for tight installations. Operating temperature range spans from -45 degrees F to 250 degrees F, supporting use across refrigeration, HVAC, and hydraulic instrumentation applications. Licensed HVAC technicians, plumbers, and instrumentation mechanics typically install this valve in low-to-medium pressure tubing circuits where repeatable shutoff and throttling are required.

This needle valve is suited for residential and light commercial applications where 3/8-inch OD tubing is used in refrigerant, water, or pneumatic lines. It fits inline in compression-fitted tubing runs and is appropriate for service valves, gauge manifold isolation, and flow-control points in small fluid systems. The compression-by-compression configuration eliminates the need for flared fittings, allowing installation directly onto standard 3/8-inch OD tubing at both the inlet and outlet.

Key Features

• Straight-pattern body for in-line installation in compression tubing circuits
• Compression x compression end connections for 3/8-inch OD tubing — no flaring required
• Brass body and brass needle construction for corrosion resistance in fluid service
• 150 psi maximum working pressure rating
• Wide operating temperature range: -45 degrees F to 250 degrees F
• Compact form factor: 1.78 inches overall length, 1.55 inches overall height

Compatibility

Designed as an OEM-style replacement or direct-install needle valve for systems using 3/8-inch OD compression tubing in HVAC, refrigeration, or fluid instrumentation service up to 150 psi.

Installation Notes

Installation is typically performed by a licensed HVAC technician, plumber, or instrumentation mechanic. Depressurize and isolate the tubing circuit completely before removing or installing this valve. Compression fittings must be assembled to the tubing manufacturer's specifications to ensure a leak-free seal — do not overtighten. Verify that the system fluid and operating conditions fall within the valve's rated pressure and temperature limits before returning the system to service.
