Q1: How do I choose the right size cap/plug for my part?
A: Measure your part's outer diameter (OD). For caps, choose an inner diameter about 10% smaller than your part OD for a snug fit. For plugs, match the plug OD to your hole ID. Send us your dimensions if unsure.
Q2: Do you have a size chart or can you send samples to test fit?
A: Yes, a full size chart is in the images above. We recommend ordering a sample kit with multiple sizes to confirm fit before bulk order. Sample cost is refundable against your first bulk order
Q3: What is the temperature range of your silicone caps/plugs?
A: Standard silicone: -60°C to +200°C continuous, up to 230°C short-term . For powder coating masking, our high-temp grade withstands up to 316°C . Tell us your process temperature.
Q4: Do you offer custom sizes or colors for standard caps?
A: Yes. We can adjust wall thickness or length for a better fit, and customize colors. Custom size requires a drawing and MOQ of 1,000 pcs. Standard colors: natural/translucent, black, red, blue.
