Parker 4BLP4-316 Compression Tube Plug 1/4 in Od Ss

Product Description

The PARKER 4BLP4-316 is a compression-style tube plug manufactured from 316 stainless steel, designed to seal the end of a 1/4-inch outside diameter tube in high-pressure fluid or gas systems. It uses a standard compression end connection with a 7/16-20 thread and is rated for working pressures up to 10,300 psi. The plug is built for demanding environments, with a temperature range spanning from -425 degrees F to 1,200 degrees F. It is installed by plumbers, pipefitters, and instrumentation technicians working on hydraulic, pneumatic, chemical, or process piping systems where a secure, leak-free tube termination is required.

This compression tube plug is suited for use in industrial, commercial, and process instrumentation applications where stainless steel corrosion resistance and high-pressure performance are required. It is appropriate for systems carrying aggressive fluids, gases, or high-purity media. The 1/4-inch OD tube size is a common instrumentation and small-bore process line dimension, making this plug a standard choice for capping unused ports or sealing tube ends during system commissioning or maintenance.

Key Features

• Stainless steel construction provides corrosion resistance in harsh fluid and chemical environments
• Rated to 10,300 psi maximum working pressure for high-pressure system use
• Wide temperature rating from -425 degrees F to 1,200 degrees F suits cryogenic through high-heat applications
• Compression end connection allows installation without welding or soldering
• 7/16-20 thread size and 1/4-inch OD tube fit are standard instrumentation dimensions
• Compact overall length of 0.5 inches for tight-space installations

Compatibility

Designed as an OEM-style compression tube plug for 1/4-inch outside diameter tubing in high-pressure instrumentation and process piping systems.

Installation Notes

Installation is performed by qualified pipefitters, plumbers, or instrumentation technicians. Depressurize and isolate the tube line completely before removing any existing fittings or installing this plug. Ensure the tube end is cut square and deburred before seating the compression ferrule. Follow applicable codes such as ASME B31.3 for process piping when integrating compression fittings into pressurized systems.
