Power Kit Umarex T4E HDB/TB 68 7.5J - 50J+

With this kit you will increase the muzzle energy of the RAM marker Umarex T4E HDB/TB 68 (7.5J version only) to more than 50 Joules (depending on the ammunition used). With higher energy, the shot capacity per one CO2 cartridge is reduced.

PRINCIPLE OF OPERATION

The Power Kit contains 2 main components that must replace the original parts in the marker: the restrictor (round plate) and the valve pin (cylinder with thread). Thanks to the use of stainless steel they provide better sliding properties and protection of the O-rings, and at the same time they are more resistant to the cooling effect of the flowing CO2 gas.

• The restrictor with a larger opening allows faster flow of CO2 gas from the cartridge into the valve.
• The modified valve pin ensures longer valve opening, so in combination with the tuning restrictor you achieve higher muzzle energy at the cost of higher air consumption.

INSTALLATION PROCEDURE

• Installing the restrictor is simple – first remove the original restrictor located inside the CO2 cartridge chamber and replace it with the new one using the supplied screw.
• Installing the valve pin requires complete disassembly of the marker. You need to (preferably with a hot air gun) heat the valve (the blackened cylindrical part) in which the original valve pin is screwed in (it is necessary to soften the threadlocker). Then install the new valve pin using the included Allen key and reassemble the marker.
• At the same time, we recommend checking for the presence of a valve block, which is often found in lower-powered models. It is a metal component above the restrictor which, during disassembly of the marker, can be knocked out backwards after unscrewing the brass plate with the activation indicator.
