Does Your Sidewall Furnace Vent End in an Open PVC Pipe?
A pipe opening that points outward can be exposed to birds, rodents, insects, leaves and windblown debris. The LGQF-LL 2 Inch U-Bend PVC Termination Vent Cap turns the outlet back downward and adds a fixed stainless steel screen without sealing the furnace vent.
- Designed for compatible 2-inch Schedule 40 PVC furnace vent pipe
- Outer-fit socket for pipe measuring 2.36–2.375 inches outside diameter
- 180-degree return bend places the screened outlet downward
- Integrated 304 stainless steel screen helps deter pests and outdoor debris
- Condensation drainage opening gives incidental moisture a path out
- Made for compatible sidewall furnace intake and exhaust terminations
The Shape Explains What the Product Does
The U-shaped body returns the outlet through approximately 180 degrees, so the screened end faces downward beside the incoming pipe. The images below show the complete product and the direction of the return bend.
Three Checks Before You Put It in the Cart
1. Confirm the Pipe
The existing sidewall termination must be compatible PVC pipe, not another pipe material.
2. Measure the OD
Measure across the outside of the pipe. This cap is intended for an actual outside diameter of 2.36–2.375 inches.
3. Check the Manual
Confirm that the furnace manufacturer permits a screened 180-degree return-bend termination at that location.
A “2 inch” label describes nominal pipe size. It does not replace an outside-diameter measurement.
Why the Details Matter at an Outdoor Termination
180° Return-Bend Body
The one-piece PVC body turns the outlet back downward. No separate return elbow is needed at the cap connection.
304 Stainless Steel Screen
The fixed screen helps deter birds, rodents, insects, leaves and larger debris while leaving an open path through the termination.
Condensation Drainage Opening
The drainage feature provides a path for incidental moisture that reaches the outlet area. It does not guarantee that frost or ice can never form.
Outer-Fit Socket
The open socket slides over compatible pipe measuring 2.36–2.375 inches OD. Verify that the connection is secure and permitted for the system.
A Furnace Vent Accessory Has Clear Limits
The return bend and screen must be allowed by the furnace manufacturer. This cap cannot override appliance instructions, vent-length calculations, permitted fittings, airflow limits or required clearances.
- Use only for a compatible sidewall furnace intake or exhaust termination.
- Do not use this model as a vertical rooftop termination.
- Do not treat it as a sealed cap, backdraft damper, check valve or safety control.
- Do not install it on incompatible pipe material or an unverified outside diameter.
- Confirm that the appliance permits both the 180-degree turn and the stainless steel screen.
- Keep the outlet and screen accessible for inspection and required maintenance.
- Maintain manufacturer-required clearances from grade, snow, openings and nearby terminations.
What Customers Say After Checking the Fit
The most useful comments are usually the simplest. Customers want to know whether the part fits the intended pipe, feels secure and looks properly made.
“Perfect fit!”
“Works great.”
“Looks like pretty good quality.”
These are individual customer experiences. Pipe condition, dimensions and installation requirements can differ, so measure and verify the furnace instructions first.

For People Who Would Rather Measure Once Than Guess Twice
Good home maintenance is often quiet work: noticing a vulnerable exterior opening, checking the equipment manual and choosing the part that matches the actual system. It is less dramatic than repairing a problem later—and that is exactly the point.
LGQF-LL makes practical vent protection for homeowners and installers who value clear fit information, durable materials and realistic expectations. This product is not a universal solution. It is a specific termination for a specific pipe and an approved application.

Frequently Asked Questions
What size pipe does this U-bend vent cap fit?
It is designed as an outer-fit cap for compatible 2-inch Schedule 40 PVC pipe measuring 2.36–2.375 inches outside diameter. Measure the actual pipe before ordering.
Does the U-bend insert inside the pipe?
No. The open socket slides over the outside of compatible pipe. It is not an internal insert or hub-style screen.
Why does a 2-inch pipe measure about 2.36–2.375 inches outside?
Two inches is the nominal pipe size. The actual outside diameter is larger, which is why measuring the existing pipe is essential.
What is the difference between U-bend and 180-degree return bend?
They describe the same general configuration on this product: the PVC body curves back so the screened outlet faces downward beside the incoming pipe.
Can it be used on both furnace intake and exhaust terminations?
It is designed for compatible sidewall furnace intake and exhaust terminations, but only when the furnace manufacturer permits the pipe size, return bend and screened outlet.
Does the U-bend guarantee better rain protection than a 90-degree cap?
No universal performance comparison can be guaranteed. The return bend places the outlet downward, but weather exposure also depends on placement, wind, wall orientation and installation.
Will the stainless steel screen restrict airflow?
Any screen and additional bend can affect a vent system. Confirm permitted termination fittings, equivalent vent length, screening and maintenance requirements in the appliance instructions.
Does the condensation drainage opening prevent freezing?
No. It provides a path for incidental moisture but cannot guarantee that frost or ice will not develop. Temperature, condensation, wind, snow, placement and appliance operation all matter.
Can this U-bend be installed as a roof vent cap?
No. This page describes a 2-inch outer-fit U-bend intended for compatible sidewall furnace terminations, not a vertical rooftop termination.
Should the cap be glued to the pipe?
Follow the appliance instructions and local installation requirements. Do not use adhesive or permanently modify the termination unless the applicable instructions permit it.
Confidence Starts With a Tape Measure and the Furnace Manual
Confirm compatible PVC, measure a 2.36–2.375 inch pipe OD and verify that the return bend and screen are permitted. When those details agree, you are choosing for the real system—not guessing from a nominal label.

Important Installation Notice
Always follow the furnace or appliance manufacturer’s installation instructions, local building requirements, allowable vent length, airflow limits and termination clearances. Inspect the screen periodically and remove external accumulation only when the appliance is safely shut down and the manufacturer’s maintenance instructions permit access.
