Eastman K2037LF 3/8" x 1/4" Lead-Free Compression Adapter

The Eastman K2037LF is a 3/8" x 1/4" compression adapter built for behind-the-wall and under-fixture rough-in work where a supply line needs to transition between two compression tube sizes. This lead-free adapter is designed for plumbers and contractors making up water supply connections at stops, valves, and fixture tailpieces, and it provides a straightforward compression-to-compression joint without soldering or solvent welding. As a lead-free (LF) fitting, the K2037LF is intended for potable water supply applications where lead-free construction is required.

Key Features

  • Trade Size: 3/8" x 1/4" reducing configuration for connecting dissimilar compression tube sizes in a single fitting.
  • Compression Connection: Compression-style ends on both sides allow a mechanical, solder-free joint for quick installation and future serviceability at supply stops and fixture connections.
  • Lead-Free Construction: Manufactured as a lead-free (LF) fitting for use in potable water supply lines where lead-free components are specified.
  • Adapter Function: Purpose-built to step down or transition a 3/8" compression line to a 1/4" compression line, commonly used for ice-maker, faucet, and toilet supply runs.
  • Rough-In Ready: Compact adapter body suited for tight under-sink, under-fixture, and behind-the-wall supply connections.

Technical Specifications

  • Trade Size: 3/8" x 1/4"
  • Connection Type: Compression x Compression
  • Lead Status: Lead-Free (LF)

Typical Applications

  • Residential and Commercial Rough-In Plumbing

Eastman K2037LF – Frequently Asked Questions

1) What does the Eastman K2037LF adapter actually connect?
It joins a 3/8 inch compression tube to a 1/4 inch compression tube, with compression ends on both sides. That makes it a step-down between two dissimilar compression supply sizes, no soldering or solvent welding involved.
2) Can I use the K2037LF on a drinking water line?
Yes. The K2037LF is a lead-free (LF) fitting made for potable water supply lines where lead-free components are specified.
3) I need to run a 1/4 inch line to an ice maker off a 3/8 inch stop. Is this the fitting?
That is exactly the transition it is built for. The adapter steps a 3/8 inch compression line down to 1/4 inch compression, which is the common run for ice makers, and also gets used on faucet and toilet supply lines off supply and angle stops.
4) Do I need a torch or solder to install this adapter?
No. Both ends are compression, so the joint is mechanical. You tighten the nut and ferrule onto the tube. That also means the connection can be taken apart later for service, which matters under a sink where you may need to pull a supply line again.
5) What is the exact part number to order for the Eastman 3/8 to 1/4 lead-free compression adapter?
Order Eastman K2037LF. That is the manufacturer part number, and it is a single configuration: 3/8 inch by 1/4 inch, compression by compression, lead-free. There are no finish or size options to specify.
6) Is this adapter a compression fitting on both ends, or does one side thread into a stop?
Both ends are compression. There is no male or female pipe thread on it, so if you need to thread into an angle stop or a fixture tailpiece with threads, this is not the fitting for that joint.
7) Is the Wiremold 1126A-3/4 adapter an alternative to the Eastman K2037LF compression adapter?
No - the two are unrelated parts that share only the word adapter. The Eastman K2037LF is a 3/8 inch x 1/4 inch lead-free compression x compression fitting for potable water supply connections at stops, valves, and fixture tailpieces. The Wiremold 1126A-3/4 is a 525 Series aluminum adapter for IPS presets, an electrical raceway component. If you are transitioning a 3/8 inch compression supply line down to 1/4 inch for an ice-maker, faucet, or toilet run, the K2037LF is the part; the Wiremold piece will not make a water-tight compression joint.
8) Will this fit in a tight under-sink cabinet?
The K2037LF has a compact adapter body meant for tight under-sink, under-fixture, and behind-the-wall supply connections, which is the space it was designed around.
