FAQs About Square/Rectangle Black Plastic End Caps ❓
How do I pick the right size end cap for my square/rectangle pipe?
Measure the outer width and height of your pipe/leg (not inner dimensions) and match it to the cap’s W*H size. For example, a 25*25mm square pipe needs a 25*25mm cap—cap sizes correspond to pipe outer dimensions for a snug fit.
Can these end 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 sets) or exposed exterior pipes.
What if my pipe’s wall thickness is over 2mm? Will the cap fit?
For pipes thicker than 2mm, trim the cap’s inner clamping edges slightly with scissors or a utility knife to create extra space. Then push or gently tap the cap into place—it will still form a secure seal.
Are these caps reusable if I need to remove them?
Absolutely! Gently pry the cap off with a flathead screwdriver (avoid excessive force to prevent damage). PE plastic retains its shape, so you can reuse the cap on the same or similar-sized pipes/legs.
Which quantity pack should I choose for home use?
For most home projects: 8pcs~20pcs (covers a dining set, shelf unit, or small furniture). If you’re doing a single repair, 1pc~3pcs works—we offer flexible packs to fit your needs!
