The Red Head Brass Commitment to
Quality and Safety in Aluminum Adapters 

All aluminum adapters are not created equal. The Red Head Brass quality advantage is built into every aluminum adapter we sell. Look for the following features:

All Red Head aluminum adapters are hardcoat anodized per MIL-A-8625 Type III, Class 1. No dye or coloring is used. This process provides the completed part with a hardened surface that resists corrosion, abrasion, and reduces electrolysis. It also prevents excessive wear on the threads. Complies with NFPA 1963, 4.12 Corrosion Resistance.



Swivels are attached as follows:
1″ thru 2″ with  6061-T9 aluminum piston rings. 

21⁄2″ thru 31⁄2″ with  #316 stainless steel ball bearings. 

4″ thru 6″ with  6262-T9 aluminum roller bearings. 


Made from  6061-T6 aluminum seamless extrusions .
 Meets ASTM B221.

Threads conform to the following specifications, including a blunt start first thread known as the Higbee located in line with the Higbee indicator on the lug.
     Federal Handbook H28/10  
     USDA 5100-190 C Tables 1-4  
     NFPA 1963 5.1 thru 5.6.4

Lathe cut synthetic or EPDM gaskets.

 Permanent roll stamp marking . Part identification is stamped into the aluminum prior to hardcoat finish. Complies with  USDA 5100-190 C 3.4 .

 RED HEAD SPECIFICATIONS: Aluminum Adapters shall be fabricated from seamless extruded 6061-T6 aluminum and hardcoat anodized per MIL-A-8625 Type III, Class 1. Threads shall be blunt start Higbee cut with indicators on adjacent lugs. Part identification shall be permanent and stamped prior to hardcoat. Swivel attachment must be metal rings or bearings, not swaged. Gaskets shall be lathe cut ozone free EPDM or synthetic rubber. Adapters and components must meet the requirements of NFPA 1963.
