Pvc Termination Cap Mesh Screen Vent Cover (RAVEN) — 2″ ID

The 2″ inner diameter (ID) and 2-3/8″ outer diameter (OD) version uses a stainless steel wire mesh round screen. It is best for HVAC exhausts and vent terminations that require a compact cap with wind- and moisture-tolerant construction. This cap is best for outdoor installations where elbows or adapters (sold separately) can connect to the ventilation system. Caution: ensure you purchase the correct adapter for a proper fit, as the product does not include elbows or couplings.
- Best for compact vent terminations on small-diameter pipes
- Better for outdoor installations with exposed piping
- Avoid if you need an all-in-one kit with adapters
3 Inch PVC Vent Termination Cap (FMTDLOG) With Stainless Mesh

This cap features a 3″ inner diameter and a 3.54″ outer diameter. Built-in condensation drainage slots and a protective Type 304 stainless steel screen help prevent moisture buildup and keep leaves and debris out of roof vents. It’s a good choice for roof vents and high-humidity areas where drainage is important. Caution: confirm outer diameter compatibility with your existing elbows or adapters before purchase.
- Best for roofs and high-humidity vent sites
- Better for preventing water buildup and blockages
- Avoid if your system uses a non-standard adapter size
Pvc Termination Cap Mesh Screen 3″ (RAVEN) — 3″ ID

This 3″ inner, 3.5″ outer diameter cap includes a stainless steel mesh screen to block pests and debris while allowing venting. It’s suitable for larger outdoor vents, furnace terminations, and sewer vents. Best for systems that can accommodate a 3″ cap without tight space constraints. Caution: adapter or elbow must be purchased separately for proper fit.
- Best for larger outdoor vent terminations
- Better for durability in exposed locations
- Avoid if space around the vent is limited
2 Inch PVC Vent Termination Cap With Stainless Mesh (FMTDLOG)

With a 2″ inner diameter and 2.36″ outer diameter, this cap connects to standard couplings, elbows, or adapters (sold separately). It features symmetrical condensation drainage slots and a corrosion-resistant Type 304 stainless steel screen. Best for compact HVAC intakes and exhausts where moisture management is needed. Caution: verify outer diameter aligns with your elbow or coupling before buying.
- Best for compact furnace and water heater vent runs
- Better for blocking moisture buildup with drainage slots
- Avoid if your system requires a different diameter than stated
Pvc Termination Cap With 2″ Stainless Screen (SViyatp) — 2 Pack

This 2″ inner diameter cap (2.39″ outer diameter) ships in a two-pack. It combines durable PVC with a stainless steel mesh to block pests while allowing airflow. It fits pipes connected to high-efficiency furnaces, steam systems, roof vents, and more. Caution: ensure correct outer diameter to match your coupling, elbow, or hub (not included).
- Best for multi-vent projects needing two caps
- Better for long-term outdoor use due to stainless mesh
- Avoid if you require a different ID/OD than specified
Buying Guide: Key Purchase Considerations
What size do you need? Start by measuring the pipe’s outer diameter (OD) and compare to the cap’s inner diameter (ID). The cap must grip or sit just outside the pipe, with adapters, elbows, or hubs purchased separately as needed. How durable should it be? Stainless steel mesh offers corrosion resistance for outdoor use, while all-plastic options may suffice indoors or in sheltered areas. Do you need drainage? Caps with built-in condensation drainage slots help prevent moisture buildup and clogs. Will pests be an issue? Stainless mesh screens narrow gaps to block debris, leaves, and small animals without restricting airflow. Are adapters included? Most listings note that elbows, couplings, or hubs are sold separately—plan for these in your overall install. Finally, consider the overall footprint: larger IDs/ODs fit bigger vents but require more space around the termination point.
How to Choose Between These Options
- Best for compact, 2-inch vent lines: 2″ IDs with compatible 2.36″–2.39″ OD
- Better for larger roof vents: 3″ ID with 3.5″ OD options
- Choose this if you need multi-pack coverage: SViyatp 2-pack
- Avoid if you cannot source the required adapters or hubs
