Description
Secutor Gas Expansion Chamber
This is a gas expansion chamber from Secutor, sold as a replacement or upgrade part for Secutor gas replicas. Secutor is known for its Roman-themed range of gas pistols and accessories, and supplying individual internal parts lets owners maintain their replicas for longer.
The product name does not list a specific model, so please check with us or compare the photos against your replica before ordering. Internal parts often differ between models even within one brand.
What a gas expansion chamber does
In many gas replicas the gas released from the magazine or reservoir passes through a chamber before it reaches the BB. This space gives the gas room to expand and settle, which can help produce a more even push on the BB from shot to shot.
Because it sits in the gas path, the condition of the chamber and its seals affects efficiency. A cracked chamber or worn seal leads to gas loss and weak or inconsistent shots, so replacing it can bring a tired replica back to normal performance.
Fitting
Internal parts like this usually require partial disassembly of the replica. Make sure the replica is unloaded and fully degassed, work on a clean surface, and keep track of small springs and pins. If you are not confident, have the part fitted by a technician.

Compatibility
Intended for Secutor gas replicas. The exact models it suits are not stated in the product name, so confirm compatibility with your replica before ordering; contact us with your model if you are unsure.
Care and maintenance
Keep seals in the gas system supple with a small amount of silicone oil, and avoid petroleum-based lubricants that can damage rubber. Use the gas type recommended for your replica and never mix gases.
Store gas replicas and magazines in a moderate temperature, away from direct sunlight and cold garages, as extreme temperatures stress seals and affect performance.
Who is it for?
For Secutor owners repairing or refreshing the gas system of their replica, and for technicians who keep spare parts for the range.
Please note: Check compatibility with your model before ordering. Always wear suitable eye protection when testing a gas replica.
