## Description

Product description

Review: Excelente producto, económico y resuelve - Excelente producto, tenía una fuga de gas en mi unidad de aire acondicionado, llenaba el gas y a la semana ya quedaba si gas, aplicamos este producto con una carga de gas completa y ya llevamos mas de 3 meses y la fuga está controlada, me salvo de cambiar toda la tubería o hasta de cambiar la unidad porque al parecer la fuga estaba en el compresor y era muy complicado de reparar y en un equipo de 10 años casi ya no valia la pena, así que este producto le dió tiempo extra a la unidad.
