Description

Overview

The Nitto style automatic socket connects 3/8in inside-diameter air hose to a matching male quick-connect plug. Its straight hose-barb tail and one-touch female coupling suit workshop lines where tools, inflators or service hoses need to be connected and removed regularly.

Features

• One-touch socket action allows a matching plug to be inserted without manually retracting the sleeve.
• Internal shut-off valve closes the air supply when the plug is disconnected.
• 3/8in ribbed hose barb suits compatible air hose with the correct clamp.
• Knurled release sleeve provides grip when disconnecting pneumatic equipment.

Specifications and Materials

This straight coupling uses a plated-steel body, female Nitto-style socket profile and 3/8in hose-barb connection. The socket contains the locking balls, spring mechanism and shut-off valve as one complete assembly. Select a hose clamp suitable for the hose construction and working pressure.

Part number: 08-GA30SH.

Compatibility and Fitment

Match the Nitto style automatic socket to the plug profile and the hose inside diameter before ordering. The most common mistake is selecting a 3/8in thread connection instead of a 3/8in hose barb, or combining different industrial coupling profiles that look similar but will not lock and seal correctly.

Compliance and Safety

Isolate and depressurise the air line before installation. Push the hose fully over the barb, position the clamp behind the final rib and confirm that the hose cannot pull free. After reconnecting the air supply, check the barb, sleeve and plugged connection for leakage.

Trailer Applications

Workshops use this coupling on compressor hoses, hose reels, tyre-inflation lines, blow guns and pneumatic tools. It also suits mobile trailer and heavy-vehicle service equipment where a removable air connection is required at the end of a 3/8in hose.
