Tag : Russian GP-4U Gas Mask

Gas masks have played a crucial role in protecting military personnel and civilians from chemical, biological, radiological, and nuclear (CBRN) threats for decades. Among the various gas masks developed and utilized around the world, the Russian GP-4U stands out as a notable example. In this blog post, we will delve into the history and service years of the Russian GP-4U gas mask.

The GP-4U Gas Mask: Overview

The GP-4U is a Soviet-era gas mask that was initially designed for use by military personnel during the Cold War period. It was developed to provide protection against a range of CBRN agents, including toxic gases and airborne particles. This gas mask is known for its distinctive and iconic appearance, characterized by a gray rubber facepiece with dual circular eyepieces and a simple exhale valve.

Service Years

The GP-4U gas mask was introduced into service in the Soviet Union in the 1960s and continued to be used by various branches of the Soviet military and civil defense organizations throughout the 1970s and 1980s. It played a significant role in safeguarding individuals against the potential threat of chemical and biological agents during the height of the Cold War.

One of the notable features of the GP-4U was its compatibility with a wide range of filters. These filters were designed to trap and neutralize harmful contaminants from the air, ensuring that the wearer could breathe safely in a contaminated environment. While the specific duration of service for the GP-4U may vary among different units and regions, it remained a critical piece of protective equipment during its active years.

Design and Features

The GP-4U gas mask was constructed with durability and functionality in mind. Some of its key design elements and features include:

  1. Rubber Facepiece: The facepiece was made from a gray rubber compound, which provided a comfortable and secure fit for the wearer.


  1. Dual Eyepieces: The GP-4U featured two circular eyepieces, each with a removable, threaded metal ring for attaching and securing the lenses.
