The Red Head Brass Commitment
to Quality and Safety in Storz Couplings

Red Head’s high quality Storz couplings have no peer. Our Storz heads are forged as required by the DIN standards for firefighting applications…not cast. The tail pieces are made from extruded aluminum…not castings or plastics. Collars are made from high strength aluminum extrusions…not cast. Review our quality below, and then insist on the
best: Storz couplings from Red Head Brass.


Tail piece and collars made from  6061-T6 aluminum seamless extrusions. 
Meets  ASTM B221. 

All Storz Heads up to 6″ are  forged 6061-T6 aluminum  to  Spec.  
 SAE-AMS-QQ-A-367  and  ASTM B247.
Complies with DIN standards. 


Stainless Steel Lock Lever
assembly configuration:
Lock Lever is an  investment casting of 304 stainless steel    ASTM A743. 
Lock Lever Spring is  316 stainless wire  passivated  AISI 316. 
Lock lever mounted with  18-8 stainless steel  shoulder bolt.

Collars are assembled with 3⁄8-16 socket head cap screw made of a high tensile alloy to  ASTM A574  with Zinc Yellow Dihchromate coating to  QQ-Z-325, Type II. 

All aluminum components are  Hardcoat Anodized  per  MIL-A-8625 Type III, Class 1. 

High quality molded Storz gaskets made using  Buna-N material.  This material is resistant to most hydrocarbons, oils, gasoline, acids and greases.

 RED HEAD SPECIFICATIONS: Aluminum Storz Hose Couplings shall consist of Storz coupling heads machined from forged 6061-T6 aluminum and coupling components fabricated from seamless extruded 6061-T6 aluminum. All aluminum components shall be hardcoat anodized per MIL-A-8625 Type III, Class 1. Part identification shall be permanent and stamped or forged prior to hardcoat. All 4″, 5″ and 6″ coupling heads shall include a stainless steel external spring-loaded lock. Storz gaskets shall be molded Buna-N rubber.
For field reattachable couplings add: The couplings shall have a tail piece sized to match hose diameter and matching segmented, bolted clamp collars fabricated from seamless extruded 6061-T6 aluminum. Couplings and components must meet the requirements of NFPA 1963.
For expansion type couplings add: Swivel and tail gaskets shall be lathe cut ozone free EPDM or synthetic rubber. Expansion rings must be smooth and well rounded soft anneal seamless red brass per UNS 23000. Couplings and components must meet the requirements of NFPA 1963.
