5000 PSI First Strike Pro Burst Disk (Safety Membrane)

First Strike Pro Burst Disk 5000 PSI – Compact Protection for Your HPA System

Safety is the number one priority when playing with High-Pressure Air (HPA). The First Strike Pro Burst Disk 5000 PSI is a specially developed safety diaphragm that protects your bottle and regulator from dangerous over-pressurization. Designed for the high-pressure side of the regulator, it acts as a controlled "weakest link" – if the pressure in the bottle exceeds the safe limit of 5000 PSI (e.g., due to heat or filling errors), the membrane bursts in a controlled manner, safely releasing gas and preventing catastrophic vessel failure.

The "Pro" series differs from standard burst disks in its construction. While common safety valves have a tall hexagonal head prone to damage or snagging, the Pro version is designed to be low-profile. Once installed, it protrudes only minimally, giving your setup a clean look and increasing durability in dense brush or CQB environments. The disk is made from a premium alloy with a precisely defined burst strength, ensuring activation occurs exactly at the rated pressure.

Key Features and Benefits:

• Low-profile design (Pro) to reduce the risk of snagging on gear

Frequently Asked Questions (FAQ):

1. Why is this disk labeled "Pro"?
The "Pro" designation refers to the low-profile screw head. While standard disks have a protruding head, this version sits nearly flush with the regulator body, increasing snag resistance.

2. Is this 5000 PSI disk suitable for my 3000 PSI tank?
Yes, exactly. The industry standard for safety protection on 3000 PSI tanks is a 5000 PSI Burst Disk on the regulator's input side. This margin ensures protection against critical over-pressurization while allowing for normal fill fluctuations.

3. How do I know if the burst disk has blown?
If the disk activates, you will hear a loud hiss and air will escape through the small vent holes on the side of the disk screw. In this case, the internal membrane is destroyed and the entire unit must be replaced. Never attempt to plug the holes.
