Ø19.5H10 Rubber Plug – Export Quality

The Ø19.5H10 rubber plug is used for conveyors, pipelines and industrial components. Outer diameter 19.5 mm, height 10 mm. Durable rubber material with tight sealing, electrical insulation and good anti-aging properties – suitable for many working environments.

Tight seal – anti-leak

Grips pipe openings/joints tightly, limiting dust, water and contaminants from entering – keeping equipment protected and stable.

Durable – anti-aging

Elastic, wear-resistant rubber; less prone to cracking or hardening under common working conditions.

Heat-resistant & insulating

Performs well in common temperature ranges; non-conductive material for safe installation.

Guidelines for sizing & storage
Notes when choosing rubber plug size for ceramic pots
During ceramic pot production, uneven shrinkage during high-temperature firing can alter the actual size of the drainage hole, especially its diameter. Based on field surveys and customer feedback, if the pot hole diameter is 19.5 mm, a suitable plug size is usually in the range of 19.5–20 mm depending on tolerances, ensuring a snug fit without looseness or leakage.
Recommendation: carefully measure the inner diameter (ID) of the pot hole with a vernier or digital caliper before choosing the plug size.
Store in a cool place, away from direct sunlight and temperatures > 40 °C. Occasionally rinse with water and dry to extend service life.
What hole size does the Ø19.5H10 plug fit best?
Recommended hole size: 19.5–20 mm (depending on actual tolerance). Measure accurately with a caliper before ordering.
Do you manufacture with custom colors/hardness?
Yes. We support custom colors (black/white/others), Shore A hardness, packaging and logo printing on request.
Recommended working temperature?
Standard: -45 °C → 70 °C (reference). For high-temperature environments, choose silicone or heat-resistant versions.
How to store for long service life?
Keep in a cool place, avoid direct sunlight and temperatures > 40 °C. Clean and dry periodically.
