CA-Fire STORZ Series Male-Female Thread Couplings

(Quick-Connect Core Accessory for Seamless Firefighting Equipment Integration)

 

1. Product Name & Positioning

 

Full Name: CA-Fire STORZ Series Firefighting Couplings (Aluminum Alloy/Brass Material, 1.5"/2.5" Sizes, Male-Female Thread Design, ISO/CCC Certified)

Abbreviation: CA-Fire STORZ Fire Couplings

Core Positioning: A high-performance quick-connect accessory for firefighting systems-fundamentally different from all previous main equipment (nozzles,hydrants,generators). It serves as the "connection hub" between fire hoses,nozzles,hydrants and foam systems, enabling fast,leak-proof assembly of fire suppression setups. Made of durable aluminum alloy/brass with STORZ standard compatibility, it solves the "connection inefficiency" and "leakage risk" of generic couplings-ideal for fire departments,industrial facilities,municipal fire systems and emergency rescue teams needing reliable equipment integration.

 

2. Core Product Advantages

 

1. STORZ Standard Quick Connection: Save Critical Rescue Time

Adopting global STORZ coupling standards, it enables one-handed quick docking:

No complex threading or tooling required-align and lock with a 90° rotation, completing connection in 3 seconds (vs. 30+ seconds for generic threaded couplings). This is vital for emergency fire rescue where every second counts.

The self-sealing design ensures no water leakage during connection/disconnection, avoiding pressure loss in fire systems (a common flaw of non-standard couplings).

2. Dual Material Options: Adapt to Diverse Use Scenarios

Offering aluminum alloy and brass variants to meet different demands:

Aluminum Alloy: Lightweight (≤0.8kg per unit),cost-effective, ideal for mobile scenarios (e.g., fire truck hoses,portable nozzles) where weight reduction is key.

Brass: Corrosion-resistant,high-pressure resistant (≥1.6MPa), suitable for harsh environments (e.g., coastal areas,chemical plants) or long-term fixed installations (e.g., hydrant connections). Both materials pass ISO/CCC certification for quality assurance.

3. Broad Compatibility: Fit Global Firefighting Equipment

Designed to match CA-Fire's full line of products and international standards:

Compatible with CA-Fire's fire hoses,QLD series nozzles,SN/SNJ series hydrants and PF series foam generators. It also fits third-party STORZ-standard equipment, eliminating "compatibility bottlenecks" in mixed-system setups.

Available in 1.5"/2.5" sizes, covering most common firefighting equipment calibers (65mm/80mm), no need for custom adapters.

4. Durable & Wear-Resistant: Long Service Life in Heavy Use

Engineered for frequent connection/disconnection and harsh conditions:

Aluminum alloy variants feature anodized anti-rust coating, passing 500-hour salt spray tests; brass variants use H59-1 brass with precision machining, resisting wear from repeated docking.

The locking mechanism is reinforced with stainless steel components, withstanding 10,000+ connection cycles without failure (generic couplings typically last 3,000+ cycles).

5. Safe & Leak-Proof: Ensure System Pressure Stability

Prioritizing safety in critical fire scenarios:

Equipped with integrated nitrile rubber gaskets (resistant to water,foam concentrate and oil), forming a tight seal even under 1.6MPa working pressure-zero leakage during high-pressure water/foam transmission.

The male-female thread structure prevents accidental disconnection under pressure, avoiding dangerous pressure drops during fire suppression.

4. Applicable Scenarios

 

Fire Rescue Operations: Fire departments use it to quickly connect hoses,nozzles and hydrants, accelerating on-site fire suppression response.

Industrial Fire Systems: Chemical plants,oil depots integrate it into fixed fire pipelines, ensuring reliable connection between hydrants,foam generators and nozzles.

Municipal Fire Protection: Municipal fire networks use it for hose-to-hydrant connections, facilitating maintenance and emergency deployment.

Mobile Rescue Equipment: Fire trucks,portable fire pumps equip it for rapid assembly of temporary fire suppression systems.

Cross-Equipment Compatibility: Used in mixed-system setups (e.g., CA-Fire marine nozzles + third-party hoses), solving compatibility issues with generic couplings.

 

5. Frequently Asked Questions (FAQ)

 

What is the STORZ standard, and why is it important?STORZ is a global firefighting coupling standard known for quick,leak-proof connection. It ensures compatibility across different brands' equipment-critical for emergency scenarios where mixed equipment may be used. CA-Fire's couplings fully comply with this standard, guaranteeing seamless integration.

How to choose between aluminum alloy and brass materials?

Choose aluminum alloy for mobile use (e.g., fire truck hoses) to reduce weight;

Choose brass for fixed installations or harsh environments (coastal,chemical areas) for better corrosion resistance and durability.

Can these couplings be used with foam mixtures?Yes. The nitrile rubber gaskets are resistant to foam surfactants (compatible with CA-Fire's 3%/6% AFFF concentrates). They won't degrade or leak when used with foam-water mixtures.

What is the maximum pressure these couplings can withstand?They are rated for ≥1.6MPa working pressure, exceeding the standard requirements of most firefighting systems (1.0-1.2MPa). This ensures safety even in high-pressure foam or water transmission scenarios.
