Spears CPVC CTS Drop Ear 90° Elbow with Stainless Steel Thread Insert

The Spears CPVC CTS Drop Ear 90° Elbow is a purpose-built plumbing fitting engineered for securely anchoring fixture supply lines to wall framing. Constructed of CPVC in the CTS (Copper Tube Size) dimensional standard, this drop ear elbow features a reinforced stainless steel thread insert at the female pipe thread outlet, giving installers a durable, wear-resistant connection point that resists thread damage from repeated fixture hookups. The socket x stainless steel female pipe thread (SOCxSSFPT) configuration allows a solvent-weld connection on one end and a threaded connection on the other, making it a go-to fitting for showerheads, sillcocks, and other wall-mounted fixture drops in a 1/2" CTS size.

Key Features

  • Trade Size: 1/2" CTS (Copper Tube Size) for standard CPVC fixture supply branch lines.
  • Durable Construction: CPVC body resists corrosion, scale buildup, and chemical attack common in domestic water distribution systems.
  • Reinforced Thread Insert: Stainless steel female pipe thread insert adds strength at the threaded outlet, reducing the risk of thread stripping during fixture installation.
  • Drop Ear Design: Mounting ears with screw holes allow the fitting to be securely fastened to wall studs or backing, stabilizing the fixture connection point.
  • 90° Configuration: Directs the supply line at a right angle, simplifying routing from a wall-stub-out to a fixture outlet.
  • Connection Type: Socket (SOC) inlet for solvent welding to CPVC pipe paired with a stainless steel FPT (female pipe thread) outlet for threaded fixture attachment.

Spears DE4107-005CSS – Frequently Asked Questions

1) Will a Spears CPVC drop ear elbow connect to 1/2 inch CPVC pipe, or does it need copper?
The socket end solvent welds to 1/2 inch CTS CPVC pipe, which is the standard CPVC water distribution size. CTS means Copper Tube Size, so the fitting matches the outside diameter of 1/2 inch copper, but it is a CPVC socket and it is joined with CPVC solvent cement, not soldered. If you are coming off copper, transition first with a copper-to-CPVC adapter.
2) What thread does the outlet on the Spears DE4107-005CSS drop ear elbow take?
The outlet is a 1/2 inch female pipe thread, so a standard 1/2 inch MIP shower arm, sillcock shank, or nipple threads straight in. What sets this model apart is that the thread is a stainless steel insert rather than molded CPVC, so the threads hold up to repeated fixture removal and reinstallation without stripping. Use thread sealant appropriate for the mating metal, and do not overtighten past the point the joint seals.
3) Why use a drop ear elbow instead of a regular 90 elbow for a shower arm?
A plain 90 leaves the shower arm cantilevered off the pipe, so every tug on the head works the joint. The drop ear version has mounting ears with screw holes so the fitting fastens to a stud or to backing behind the wall. The fixture load goes into the framing instead of the pipe. For anything a person touches or pulls on, a showerhead, a sillcock, a wall-mount faucet, use the drop ear. For a direction change buried in a wall or ceiling run, a standard 90 is fine.
4) Is a stainless insert drop ear elbow worth it over an all-CPVC one?
It matters where the threads get worked. An all-plastic FPT outlet can strip or crack if a fixture is cranked down hard or swapped out a few times over the life of the wall. The stainless steel insert on the DE4107 gives a metal thread at that outlet, which is the reason to spec it on showerhead and sillcock drops in rentals, hotels, and multi-family where fixtures get changed. On a fitting that gets threaded once and never touched, the plain CPVC version does the same job.
5) Can I use this CPVC drop ear elbow on a hot water line?
CPVC is rated for hot and cold domestic water distribution, which is the whole point of the material over PVC, and this drop ear is built for exactly that service. It resists corrosion and scale in potable water systems. Keep it to water distribution though, not DWV, not compressed air.
6) What do I need besides the elbow to rough in a showerhead drop with CPVC?
The fitting itself is just the elbow. To finish the drop you also need CPVC solvent cement (and primer if your jurisdiction requires it for CPVC) for the socket joint, two screws to fasten the mounting ears into the stud or a piece of backing between studs, thread sealant for the FPT outlet, and the shower arm or nipple that threads into it. The elbow ships as the fitting alone.
7) Does the drop ear elbow have to be screwed to framing, or can it float in the wall?
Screw it down. The ears exist to stabilize the connection point, and a drop ear left unsecured is no better than a plain 90 with extra plastic on it. If there is no stud where the fixture lands, install blocking between the studs and fasten the ears to that. Set the face of the ears so the finished outlet sits at the right depth for your wall covering before you cement the socket.
8) Will this Spears fitting work for a sillcock or hose bibb stub through the wall?
Yes, sillcock rough-ins are one of its listed applications. The socket takes the 1/2 inch CPVC branch, the ears anchor to the rim joist or blocking so the bibb does not move when someone yanks a hose, and the stainless FPT outlet takes the threaded shank. The metal threads are the part that matters here, since exterior bibbs see more torque and more replacement than most fixtures.
