Parker 821FR-6-BLU-RL Push-on Air Hose 3/8 in Id 300 Psi

Product Description

The PARKER 821FR-6-BLU-RL is a blue, push-on style air hose designed for compressed-air distribution in industrial and commercial service environments. Built from synthetic rubber, it carries a 3/8 inch inside diameter and a 0.63 inch outside diameter, handling working pressures up to 300 psi across a service temperature range of -40 degrees F to 212 degrees F. This hose ships cut-to-length from a 575-foot master coil, sold in 1-foot increments with a 25-foot minimum cut. It is a staple in pneumatic system builds, tool-drop lines, and compressed-air manifold runs where a reliable push-on connection is needed.

This hose is suited for residential, commercial, and light industrial pneumatic applications where a flexible, cut-to-length air supply line is required. Typical installations include shop air systems, compressor drop lines, pneumatic tool feeds, and general compressed-air plumbing. The push-on design speeds assembly without fittings requiring clamps, making it a practical choice for service techs who build or repair air supply lines in the field. The blue color aids in quick visual identification of air lines within multi-hose installations.

Key Features

• Push-on construction for fast, tool-free hose-to-fitting assembly
• 3/8 inch inside diameter supports standard pneumatic tool and air-line fittings
• 300 psi working pressure rating suitable for typical shop-air and pneumatic service
• Wide temperature range of -40 degrees F to 212 degrees F for year-round use in varied environments
• Synthetic rubber construction provides flexibility and resistance to abrasion and weathering
• Blue color enables easy identification in multi-line pneumatic systems
• Cut-to-length availability from a 575-foot coil minimizes waste on custom runs

Compatibility

Designed for use with standard push-on pneumatic fittings sized for 3/8 inch inside diameter air hose. Confirm fitting compatibility before assembly; no end connections are included with this hose.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed-air system construction and applicable safety standards. Depressurize and lock out the air supply before connecting or disconnecting any hose or fitting. Verify that all fittings and components in the assembly are rated at or above the 300 psi working pressure of this hose. Do not exceed the rated working pressure or temperature limits of the hose or any connected component.
