Brasscraft 68-4-4X Compression X Mnpt Adapter 1/4 in

Product Description

The BRASSCRAFT 68-4-4X is a brass compression-to-male NPT adapter from the 68 Series line, designed to transition a compression tube connection to a male pipe thread fitting. At 1/4 inch on both ends, this adapter converts a compression fitting seat to a standard MNPT threaded port. It is built from brass, making it suitable for use in water, gas, and refrigeration line applications. Plumbers and HVAC technicians install this type of adapter when connecting copper or soft tubing to threaded brass or steel components in tight supply or instrument line runs.

The 68-4-4X is used in residential and light commercial plumbing and HVAC applications where a compression tube end must connect to a male NPT threaded port. Common install scenarios include appliance supply lines, instrumentation connections, and gas valve inlet fittings. The 1/4 inch compression by 1/4 inch MNPT configuration makes it a standard size for small-diameter copper or plastic tubing terminations.

Key Features

• 1/4 inch compression inlet connects to 1/4 inch male NPT outlet
• Brass construction provides corrosion resistance for water and gas service
• 68 Series design for reliable, leak-resistant compression seating
• Compact adapter profile suited for tight installation spaces
• No solder required on the compression side

Compatibility

Designed as an OEM-style replacement or service fitting for 1/4 inch compression-to-MNPT adapter applications in residential and light commercial plumbing and HVAC systems.

Installation Notes

Installation is performed by licensed plumbers or qualified HVAC technicians. Shut off the water or gas supply and depressurize the line before making or breaking any fitting connection. Hand-tighten the compression nut, then snug with a wrench — do not overtighten, as this can deform the compression ferrule and cause leaks. Apply thread sealant or PTFE tape to the MNPT threads per local plumbing code requirements before threading into the mating port.
