Buying Guide
What to consider when choosing 7 inch PVC caps:
- Diameter fit: Ensure the inner diameter matches the outer diameter of the tube or post you want to cap. If the item sits between sizes, choose the slightly smaller cap for a snug hold.
- Material: Rubber and vinyl caps offer flexible protection and edge sealing; polyethylene caps are more durable for outdoor dock and post use.
- Surface design: Flat tops are useful for posts that require a ledge or bird deterrence; rounded caps blend discreetly with cylindrical posts.
- Color and visibility: Black and white caps are common; clear variants are better for hidden installations where aesthetics are important.
- Intended environment: Outdoor, wet conditions call for weather-resistant materials; indoor fixtures can use lighter, decorative caps.
