Parker 7212-381BK Push-on Air Hose 3/8 in Id 300 Psi

Product Description

The PARKER 7212-381BK is a push-on air hose designed for pneumatic systems and compressed air lines in industrial and trade applications. Constructed from Buna-N (nitrile rubber), it delivers a working pressure rating of 300 psi and operates across a temperature range of -40 degrees F to 212 degrees F. With a 3/8 inch inside diameter and 5/8 inch outside diameter, it is sized for standard push-on fittings that eliminate the need for clamps or ferrules. This hose is sold cut-to-length in 1-foot increments with a 25-foot minimum cut length, making it practical for job-specific runs in shops, service bays, and mechanical rooms.

This hose suits pneumatic tool lines, air compressor distribution runs, and general compressed air service in residential and light commercial settings. It is commonly installed by HVAC technicians, plumbers, and general mechanics who need a flexible, clamp-free air line that routes easily through tight spaces. The push-on design speeds up assembly and reduces fitting hardware on bench-built or field-built air systems. The black Buna-N construction resists petroleum-based fluids and moderate ozone exposure typical in shop environments.

Key Features

• 28 InHg vacuum rating allows use in light vacuum applications
• Sold cut-to-length in 1-foot increments, 25-foot minimum cut length

Compatibility

Designed for use with standard push-on air hose fittings in pneumatic and compressed air distribution systems. Verify fitting outside diameter matches the 3/8 inch ID bore before installation.

Installation Notes

Installation is typically performed by qualified HVAC technicians, plumbers, or pipefitters. Depressurize and lock out the air supply before cutting or connecting hose segments. Use a clean, straight cut to ensure a full seat against push-on fitting barbs. Inspect fittings and hose ends for burrs or contamination before assembly to maintain a leak-free connection.
