Umarex T4E HDX 68 Service Kit – Seal and Spring Set

Umarex T4E HDX 68 Service Kit – Professional Maintenance for Your Shotgun

Even the most durable RAM weapon requires professional maintenance after a certain period of operation. The Umarex T4E HDX 68 Service Kit is designed to allow you to perform a complete overhaul of the sealing system and mechanical parts at home or in a service workshop. This kit is essential when detecting CO2 leaks, loss of power, or irregular operation of the loading mechanism.

The kit contents include specific O-rings made of durable polymer compounds rated for high CO2 pressures, as well as key washers and springs. It is the springs that lose their stiffness over time, which can lead to failure in ball feeding or poor valve function. With this kit, you restore the weapon to factory settings and ensure consistent performance during training or defense.

Thanks to high-quality materials, the new components have a long lifespan and are resistant to the silicone oils used for lubricating airguns. Investing in an original service kit pays off not only by extending the life of the shotgun but primarily with the certainty that the weapon will not fail you at a critical moment.

Frequently Asked Questions (FAQ):

1. When is the best time to use this kit?
We recommend using the kit when the weapon starts showing a gas leak (audible hissing) or preventatively after firing approximately 50–100 CO2 cartridges, depending on the intensity of use and lubrication.

2. Can I replace the parts myself?
Replacement requires basic technical skills and knowledge of the HDX 68 weapon disassembly. If you are unsure, we recommend entrusting the assembly to a professional service to avoid damaging delicate threads or the valve.

3. Do I need to use silicone oil when replacing seals?
Yes, we strongly recommend applying a thin layer of silicone oil when installing new O-rings. This ensures their proper seating and significantly extends their lifespan and sealing ability.

4. Are these parts suitable for the HDS 68 model as well?
No. This kit is specifically designed for the internal mechanism of the HDX 68 shotgun. The HDS model (double-barrel shotgun) has different seal and spring dimensions.
