Jaco TxF Ell, 3/8

Jaco TxF Elbow, 3/8" is a 90-degree compression fitting that connects 3/8" OD tubing to a matching 3/8" female threaded port. It combines a directional bend with a quick, tool-light tube seal, making it handy for routing small-diameter lines around valves, tanks, and feeders.

• Right-angle elbow body for 90-degree tubing turns
• Compression side accepts 3/8" OD tubing
• Female iron pipe thread (FIPT) port for threaded takeoff
• Jaco compression design using a nut and ferrule
• Molded polymer construction resistant to water corrosion

Compression elbows like this are common in chemical feed lines, brine tubing, RO plumbing, and gauge or sample-line connections where space is tight and a clean turn is required. The ferrule grips the tube as the nut is tightened, forming a leak-resistant joint without adhesives. Verify that your tubing measures 3/8" on the outside diameter and that the mating thread matches before assembly, and seal the threaded end appropriately when joining to a pipe nipple.

A Compact Tube-to-Female Elbow

The Jaco TxF Elbow joins 3/8-inch tubing to a female-threaded fitting while turning a ninety-degree corner in the run. One end grips the tubing with a compression-style connection; the other threads onto a male fitting on your valve, pump, or tank. Jaco fittings are a trusted name in water treatment plumbing precisely because these small connectors need to seal reliably and stay put, and an elbow lets you route a line cleanly into a port that would otherwise demand an awkward bend in the tube.

When This Fitting Solves a Problem

You will reach for a tube-to-female elbow whenever a feed, drain, or brine line needs to change direction to meet a threaded port at an angle. It is also a common replacement part, since fittings are exactly where a system tends to develop a slow drip after years of pressure cycling, or where an over-tightened connection has cracked. Keeping the right elbow on hand means a leak or an install does not stall over a single connection point that refuses to cooperate.

Confirm the Sizes

Because both the tube size and the female thread have to match your equipment, a quick fitment check is worth the moment it takes. Let us know where this elbow will go and the sizes you are working with, and we will make sure it is the right one before you order. We include any documentation we have available, and the Water Softener Plus team is happy to help you piece together the fittings for your project so every joint seals cleanly and holds.
