Parker MP11851 Barbed Tube Male Connector 1/4 in Od Brass 5pk

Product Description

The PARKER MP11851 is a barbed tube male connector designed for secure, leak-resistant tubing connections in fluid and pneumatic systems. The fitting accepts tubing with a 0.17-inch inside diameter and a 1/4-inch outside diameter, threading into ports via a 1/8-27 male thread. Constructed from brass, it offers corrosion resistance and durability in both liquid and gas line applications. The barbed design creates a mechanical grip on the tubing, reducing the risk of pull-out under normal operating pressures. Plumbers, HVAC technicians, and pneumatic system installers use this type of fitting as a compact, reliable solution for joining tubing to threaded ports.

This connector is suited for residential and light commercial applications where small-diameter tubing must interface with a 1/8-27 NPT-style threaded port. Typical uses include condensate drain lines, pneumatic instrument lines, refrigeration accessory circuits, and plumbing fixture supply connections. The fitting ships in a package quantity of five, making it practical for service vans or shops that need multiples on hand for common repair and installation jobs.

Key Features

• Barbed design provides mechanical retention on tubing without additional clamps in low-pressure applications
• 1/8-27 male thread for direct connection to standard NPT-compatible threaded ports
• Brass construction for corrosion resistance in both liquid and pneumatic service
• Compatible with 1/4-inch OD tubing with a 0.17-inch inside diameter
• Sold in a five-piece package quantity for efficient stocking and jobsite use

Compatibility

Designed as an OEM-style replacement fitting for systems using 1/4-inch OD tubing and 1/8-27 male-threaded ports in fluid or pneumatic circuits.

Installation Notes

This fitting should be installed by a qualified plumber, HVAC technician, or pneumatic system technician following applicable IPC or system-specific codes. Shut off fluid or air supply and relieve system pressure before removing or installing any fitting. Apply thread sealant or PTFE tape to the male threads as appropriate for the service medium. Do not overtighten the threaded connection, as brass fittings can crack under excessive torque.
