Fast-N-Tite M Conn, 1/4 MIPTx3/8 Tube, 456MC4 (P6MC4)

Fast-N-Tite Male Connector

This Fast-N-Tite male connector, part number 456MC4, transitions between a 1/4 inch male iron pipe thread (MIPT) and 3/8 inch tubing. It is a compression-style fitting designed to join tubing to a threaded port quickly and reliably, which is exactly the kind of small connection that shows up throughout drinking water and treatment plumbing. Fittings like this are used to route water lines to and from filters, valves, and dispensers where a neat, low-profile connection is needed.

When This Fitting Is Needed

You need a connector like this whenever you have to join 3/8 inch tubing to a 1/4 inch MIPT port, whether you are assembling a new run, replacing a fitting that is leaking or damaged, or adapting a line during service. Compression tube fittings are popular because they make a secure seal on the tubing without solvent or tools beyond a wrench, and they can often be disconnected and reworked when a system changes. Keeping a correct connector on hand saves a trip when you are mid-project.

Installation and Fitment

Installing the fitting generally means threading the MIPT end into its port with suitable sealant and securing the tubing into the compression side so it grips and seals properly on the tube. Getting the thread size and tube size matched to your line is essential for a leak-free joint. Because tube and thread combinations vary, it is worth confirming both ends suit your setup before ordering. At Water Softener Plus we include documentation with your order and are happy to help you verify this connector matches your tubing and port before you buy.
