Custom made soft silicone pipe plug rubber stopper

A soft silicone pipe plug offers a flexible closure for a matched pipe opening. For an application with repeated access, the exposed handling area should allow removal without stretching the same thin region each time.

ETOL adapts size, color and construction. Define insertion depth and handling clearance; easy conformity during fitting does not ensure easy extraction if the body is pushed too far.

Try the complete fitting sequence with the actual pipe before routine use. Keep its edge smooth and inspect the plug for a portion that folds inward during insertion. Release the closure through its intended handling feature under the system's appropriate service conditions. After removal, check the transition between the inserted body and exposed section for small tears. Clean the contact region before refitting, and replace a part that no longer returns to its intended shape. If removal repeatedly requires excessive force, reassess the fit and access rather than pulling harder on the soft rubber.

Material options

Silicone. Custom formulation and color for the intended contact conditions.

Hardness selection

Silicone: 20–80 Shore A. If removal repeatedly requires excessive force, reassess the fit and access rather than pulling harder on the soft rubber.

Custom dimensions
