FAQs About Square/Rectangle Black PE Plastic End Caps ❓
How do I choose the right size end cap for my square/rectangle pipe?
Measure the outer width and height of your pipe/leg (not the inner dimensions) and select a cap with matching W*H. Important: Cap sizes listed are outer diameters—always match to your pipe’s outer size (e.g., a 25*25mm pipe needs a 25*25mm cap).
Can these PE plastic caps be used outdoors?
Yes! PE plastic is weather-resistant—these caps won’t fade, crack, or degrade in rain, sun, or cold temperatures. They’re perfect for outdoor furniture (e.g., patio chairs) or exposed pipes.
What if my pipe’s wall thickness is over 2mm? Will the cap still fit?
For pipes thicker than 2mm, trim the cap’s inner clamping edges slightly with scissors or a utility knife to create more space. Then push or gently tap the cap into place—it will still form a secure seal.
Are these end caps reusable if I need to remove them?
Absolutely! Gently pry the cap off with a flathead screwdriver (avoid sharp force to prevent damage). PE plastic retains its shape, so you can reuse the cap on the same or similar-sized pipes/legs.
What’s your return policy if the caps don’t fit my pipe?
Unused, untrimmed caps can be returned within 7 days for a full refund (return shipping paid by buyer). Contact us first with your pipe’s W*H measurements—we’ll help you find the perfect size!
