General concept of grommets

A wall pass-through is a construction element or accessory used to allow the passage of pipes, cables, conduits or any installation system through walls, walls or structures without affecting the airtightness, watertightness or structural integrity of the construction. Its essential function is to guarantee an adequate seal that prevents leaks of water, air, dust or gases, preserving the conditions of the interior environment and the durability of the work.

Wall grommets are commonly used in multiple sectors such as civil construction, industrial, hydraulic, electrical and air conditioning systems, among others. Depending on the type of wall and the intended use, there are different designs and materials that meet the specific needs of tightness, mechanical resistance and durability.

Rigid grommets

Rigid wall grommets are generally made of metal materials such as stainless steel, cast iron or aluminum, or hard plastics such as PVC or polyamide. Its solid structure offers high mechanical resistance and protection against impacts or external forces. They are used when a firm seal and stable fixation for rigid pipes or conduits is necessary.

These glands can have internal or external threads to facilitate connection with pipes or accessories, and usually include sealing gaskets to prevent leaks. They are common in industrial, hydraulic installations and drinking water or wastewater systems, where safety and durability are required.

Flexible grommets

Flexible wall grommets are made of elastic materials such as synthetic rubbers, elastomers or flexible plastics that allow a certain degree of movement or vibration without losing tightness. They are ideal for installations where pipes or cables may experience displacement, thermal expansion or vibrations.
