Need to Angle a Sidewall Furnace Vent Without Using a Tight Bend?
An exposed PVC furnace vent can leave a direct opening for birds, rodents, insects, leaves and windblown debris. A compact 45 degree cap may fit a tight area, but some installations have enough clearance for a wider, more gradual curve.
The LGQF-LL 2 Inch 45 Degree Long Sweep PVC Vent Cap combines a downward-angled outlet, an outer-fit connection and a fixed 304 stainless steel screen. It is designed for compatible sidewall furnace intake and exhaust terminations—not as a general-purpose pipe fitting.
- 45 Degree Long Sweep configuration with a wider bend radius
- Downward-angled screened termination outlet
- Outer-fit connection for pipe measuring 2.36–2.375 inches outside diameter
- Compatible with correctly sized 2-inch Schedule 40 PVC pipe
- Integrated 304 stainless steel screen helps deter pests and larger debris
- Condensation drainage opening provides an exit for incidental moisture
See the Long-Sweep Structure Before Ordering
The longer curve distinguishes this product from the separate 45 Degree Short Sweep model. Long sweep describes the wider bend shape and the additional clearance it requires. It is not a promise of a specific airflow rate or furnace-efficiency improvement.
Confirm Both Pipe Diameter and Installation Clearance
1. Confirm PVC
Verify that the existing sidewall furnace termination uses compatible PVC pipe—not metal duct or flexible hose.
2. Measure the Outside
Measure straight across the pipe’s outside diameter. The required OD is 2.36–2.375 inches.
3. Check the Space
Confirm that the wider curve clears the wall, siding, nearby pipes, snow level and all required termination clearances.
“2 inch” is the nominal pipe size. This outer-fit cap is selected by the actual pipe outside diameter. Do not measure the pipe’s inside opening to determine compatibility.
What Each Part Is Designed to Do
45 Degree Long-Sweep Body
The wider bend changes the direction of the outlet more gradually than the Short Sweep model. This describes the shape—not guaranteed airflow or pressure performance.
Downward-Angled Outlet
The 45 degree outlet helps reduce direct exposure compared with an uncovered horizontal pipe. It does not provide the same downward direction as a 90 degree model and cannot exclude every weather condition.
304 Stainless Steel Screen
The fixed mesh helps deter birds, rodents, insects, leaves and larger outdoor debris. It does not turn the vent into a sealed enclosure.
Condensation Drainage Opening
The drainage opening allows incidental moisture reaching the cap to exit. It is not a replacement for the appliance’s condensate system and cannot guarantee freeze prevention.
Outer-Fit Lower Socket
The lower socket pushes over compatible pipe measuring 2.36–2.375 inches OD. Only this end connects to the existing pipe.
Open Screened Termination
The screened end is the termination outlet and must remain open. Do not attach another pipe, valve or cover to this end.
Know the Safety Boundary Before Installation
A furnace vent is part of an appliance system. The furnace or appliance manufacturer must permit the selected screened termination. This accessory cannot override the manufacturer’s instructions, 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 use it on drainage, sewer, radon, plumbing, pool or sump-pump systems.
- Do not use it on dryer vents, metal ducts or flexible hoses.
- Do not treat it as a sealed pipe cap, backdraft damper, check valve or backflow device.
- Do not connect another pipe to the screened outlet.
- Confirm allowable screening, airflow, vent length, weather exposure and termination clearances.
- Keep the screen accessible for periodic inspection and maintenance.
What Owners Noticed in Real Installations
Customer comments on this product focus on the practical details that matter after delivery: whether it fits the measured pipe, whether it feels secure and whether the selected curve works in the available space.
“Fits great on 2-in Schedule 40.”
“Works like a charm.”
“Fit great and is snug on there.”
These comments describe individual installations. They do not replace measuring the actual pipe, checking available clearance or following the furnace manufacturer’s instructions.

For Homeowners and Installers Who Measure Before They Modify
Protecting an exposed vent opening is a small maintenance decision connected to an important home system. The goal is not to cover the opening as tightly as possible. It is to choose the permitted shape, confirm the fit and keep the termination accessible for inspection.
Careful owners compare the Short Sweep and Long Sweep shapes, measure the actual pipe and check the available wall space before ordering. LGQF-LL makes those differences clear so the purchase is based on the installation—not a guess from the nominal label.

Compare the Other 2 Inch Vent Cap Shapes
The 45 Degree Short Sweep model is more compact. This 45 Degree Long Sweep model uses a wider curve and requires more installation clearance. A 90 Degree model directs its outlet farther downward.

Frequently Asked Questions
What pipe size does this 45 degree long-sweep vent cap fit?
It is designed to push over compatible 2-inch Schedule 40 PVC pipe measuring 2.36–2.375 inches outside diameter. Measure the actual pipe before ordering.
Does this vent cap insert inside the pipe?
No. The lower socket is an outer-fit connection that pushes over the outside of compatible pipe.
What does long sweep mean?
It describes the wider curved shape of the 45 degree body. It does not guarantee a particular airflow rate, pressure drop or improvement in appliance efficiency.
What is the difference between this model and the 45 degree short-sweep cap?
The Short Sweep model uses a tighter, more compact bend. This Long Sweep model has a wider bend radius and requires more wall clearance. The appliance instructions determine which configuration is permitted.
Can another PVC pipe be connected to the screened end?
No. Only the lower outer-fit socket connects to the existing pipe. The angled screened end is the termination outlet and must remain open.
Can it be used on both furnace intake and exhaust terminations?
It is designed for compatible sidewall furnace intake and exhaust PVC terminations, but only when the furnace or appliance manufacturer permits this 45 degree screened configuration.
Does the angled outlet completely prevent rain or snow entry?
No. It helps reduce direct exposure compared with an uncovered horizontal opening, but it cannot guarantee exclusion of rain, wind-driven water, frost or snow.
Does the stainless steel screen create zero airflow restriction?
No such guarantee should be made. Any screen can affect a vent system. Confirm allowable screening, airflow limits and inspection requirements in the appliance instructions.
Does the condensation drainage opening prevent freezing?
No. It provides an exit path for incidental moisture reaching the cap but cannot guarantee prevention of frost or ice. Weather, condensation, placement and appliance operation all matter.
Can this model be used on a roof, radon, drain, sewer, pool or plumbing vent?
No. This listing is intentionally limited to compatible sidewall furnace intake and exhaust PVC terminations.
Is this a backdraft damper, check valve or backflow device?
No. It is a fixed screened PVC termination vent cap and has no moving valve or damper mechanism.
Should the cap be glued to the pipe?
Follow the furnace or appliance manufacturer’s installation instructions and local requirements. Do not apply adhesive or permanently modify the termination unless the applicable instructions permit it.
Measure the Pipe. Check the Space. Then Choose the Long Sweep.
Confirm compatible PVC, measure a 2.36–2.375 inch pipe OD, allow clearance for the wider curve and verify that a 45 Degree Long Sweep screened termination is permitted.

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