Male Ell, 1/4 MIPT x3/8t, 456ME4 (P6ME4)

A Compact Male Elbow Fitting

The P6ME4 is a male elbow fitting that turns a corner in a tubing run while connecting to a threaded port. One end carries a 1/4-inch male iron pipe thread that screws into a fitting; the other accepts 3/8-inch tubing. An elbow like this lets you route a small water line neatly around an obstacle or into a port that sits at an angle, sparing you from forcing rigid tubing into a bend it does not want to hold. Small fittings like this are the connective tissue that ties a water treatment system together.

Where You Will Reach for It

Throughout a softener or filter installation there are places where a feed line, a drain line, or a brine line has to change direction to meet a valve, a pump, or a tank port cleanly. That is exactly where a male elbow comes in. It is also a frequent replacement part, because fittings are where a system tends to develop a slow weep after years of pressure cycling, or where an over-tightened joint has cracked. Having the correct thread-to-tube elbow on hand keeps a repair or an install moving instead of stalling over one stubborn connection.

Getting a Clean, Lasting Seal

A fitting only does its job if both ends match what they connect to. The male thread has to suit the port it screws into, and the tube side has to fit the tubing you are running. When those sizes line up, the elbow seats cleanly and holds under pressure without fuss. Threaded connections generally benefit from proper sealing at the threads, and the tube side seats according to its connection style, so a careful assembly here pays off in a joint that stays dry.

Confirm the Sizes First

Because both the thread and the tube size have to match your equipment, a quick fitment check saves you a return trip. Tell us where this elbow is going and the sizes you are working with, and we will confirm it is the right one before you order. We pass along any documentation we have, and the Water Softener Plus team is glad to help you sort out the fittings for your project so every connection goes together tight and stays leak-free.
