Parker 3BLP3-B Compression Tube Plug Brass 3500 Psi

Product Description

The PARKER 3BLP3-B is a brass compression tube plug designed to seal open tube ends in fluid and pneumatic line systems. It accepts a compression-style end connection, making it suitable for quick, tool-assisted installation without soldering or welding. Constructed from brass, the fitting handles a maximum working pressure of 3500 psi, making it appropriate for moderate- to high-pressure service lines. Plumbers, pipefitters, and pneumatic system technicians typically specify this type of plug when capping unused ports or terminating branch lines during system modifications or maintenance.

This compression plug is used in residential and light commercial plumbing, HVAC refrigerant line work, and industrial pneumatic or hydraulic tubing systems where a leak-free, removable end cap is required. It is suited for installations requiring a secure tube seal without permanent joining methods. The single-piece compression design keeps installation straightforward and allows the plug to be removed and reinstalled when branch lines need to be reopened.

Key Features

• Brass construction provides corrosion resistance and compatibility with common tubing materials
• Compression end connection eliminates the need for soldering or threading
• 3500 psi maximum working pressure rating suitable for moderate- to high-pressure applications
• Compact, single-unit design for straightforward tube-end sealing
• Removable and reinstallable without damaging the tubing when properly installed

Compatibility

Designed as an OEM-style compression tube plug for use with standard compression-compatible tubing in plumbing, pneumatic, and fluid transfer applications. Cross-references to Swagelok part number B-300-P.

Installation Notes

Installation is performed by plumbers, pipefitters, or qualified technicians. Before installing or removing any compression fitting, depressurize and isolate the line completely. Use an appropriate tube cutter to ensure a clean, square tube end before seating the compression fitting. Follow applicable IPC or IFGC guidelines for the system type, and verify that the tubing material and size are compatible with compression-style fittings before assembly.
