Male Fitting to HP port

• 7/16 x 20 UNF male threads
• Brass with electroless nickel plating
• Strain relief with shock absorber
• Viton O-ring

Female Fitting to SPG

Swivel-Pin Air-Spools — Please note that all high pressure hoses use a swivel pin air spool with two tiny O-rings to mate the swivel connector on the hose to the fitting on the gauge. The airspool is not included with the hose, but we recommend replacing the air-spool when replacing the hose. The standard 'shoulder' air-spool has the flange in the centre. Some SPGs, typically the plastic body ones, may only accept a 'bullet' air-spool without a shoulder. We stock the standard 'long' bullet air-spool as well as the less commonly used 'short' bullet air-spool.
