Process & quality control

1) Material selection

EPDM for weather/ozone; NBR for oil; Silicone for high temperature & safe contact.

 

2) Precision molding

Polished steel mold ensures smooth surfaces and sharp edges; tight geometric tolerances.

 

3) Post-processing & inspection

Deflashing, antistatic washing, Shore A hardness test, 100% dimensional check before packing.

Size selection & storage guide

Notes when choosing rubber plug size for ceramic pots

During ceramic pot production, uneven shrinkage when firing at high temperatures can cause deviations in the actual size of the drain hole, especially in diameter. Based on field surveys and customer feedback, if the pot hole diameter is 18 mm, the suitable plug size is 18 mm, depending on the actual tolerance. This ensures a snug fit, no looseness, and no leakage.

Recommendation: carefully measure the inner diameter (ID) of the pot hole with a caliper or digital caliper before selecting the plug size.

Store in a cool place, away from direct sunlight and temperatures > 40 °C. Occasionally soak in water and dry in the shade to extend service life.

Frequently Asked Questions (FAQ)

1. What hole size is optimal for Ø18H10?

We recommend hole Ø17.6–18.2 mm depending on sheet material & plug hardness; a light interference fit is needed to achieve proper sealing.
