The Flexmaster joint needs 240 IN-LBS of torque for proper installation.

trying to swap out an old joint, is this one actually for 3.5 inch pipe and straight through?

Question by: Tammy T on Aug 27, 2025, 9:15 PM

It’s a straight Flexmaster pipe and tube joint with female compression ends sized for 3.50 inch pipe. The listed pipe OD is 4 inches, so it’s meant to clamp and seal on that 3.5 inch pipe size using compression connections.

Got a 3.5 inch pipe that's running a little crooked coming out of a pump housing. Will this joint handle that kind of situation or do i need something else?

Question by: Jerry M on Sep 23, 2025, 2:40 PM

Angular misalignment up to 4 degrees per end is within what this joint handles, so minor pipe run deviation coming off a pump housing is exactly the kind of thing it's built for. Keep in mind the joint itself isn't meant to restrain pipe movement along the line. You'll still need hangars, guides, or anchors to hold the system in place. The joint seals the connection, it doesn't lock the pipe from shifting axially.
