Technical information and usage areas
All our products are manufactured in our facility with special recipes and quality certifications (ISO 9001:2015, RoHS, REACH).
Tapered plugs are designed in a conical shape to fit pipes, shafts, holes and internal threads. Tapered plugs offer the advantage of single product use at close diameters. They are masking plugs with high heat and acid resistance.
Tapered plugs are made from silicone compound and come in different sizes. They are among the most commonly used masking plugs. Thanks to its tapered structure going from small diameter to large diameter, it allows the same product to be used in several areas.
Material: Manufactured in our factory with our own formula silicone compounds and special activators in varying hardness (50-80 ShoreA) depending on diameters.
Post Cure: After production, it is subjected to final curing (postcure) process for 4 hours in our special ovens.
