Parker L2C Pneumatic Coupling Nipple 1/4 in 300 Psi Lincoln Stem

Product Description

The PARKER L2C is a pneumatic hose coupling nipple designed for use in compressed air and pneumatic fluid systems. Built from steel with a zinc chromate finish, this nipple provides reliable threaded connection via a 1/4-18 MNPT thread. It carries a maximum working pressure of 300 psi and an operating temperature range of -40 to 250 degrees F, making it a durable choice for demanding shop and industrial environments. The L2C belongs to Parker Series 70 and features a Lincoln Long Stem interchange profile. Installation is handled by HVAC technicians, industrial maintenance mechanics, and pneumatic system specialists.

The PARKER L2C is used in pneumatic tool connections, air compressor lines, and industrial compressed air distribution systems. Its Lincoln Long Stem interchange design allows it to mate with compatible Lincoln-style couplers found in many shop environments, automotive service bays, and light manufacturing facilities. The 1/4 inches body diameter and threaded connection type make it a common fit for standard quarter-inch pneumatic lines in both residential shop and commercial maintenance applications.

Key Features

• Lincoln Long Stem interchange profile for compatibility with widely used coupler bodies
• 1/4-18 MNPT threaded connection for secure, leak-resistant installation
• 300 psi maximum working pressure suits most compressed air applications

Compatibility

Designed as an OEM-style replacement or new-installation nipple for pneumatic systems using Lincoln Long Stem interchange couplers in Series 70 configurations.

Installation Notes

This coupling nipple is installed by qualified pneumatic system technicians or industrial maintenance personnel. Before installation, depressurize the air line completely and verify the system is locked out. Apply thread sealant appropriate for pneumatic service to the MNPT threads before making up the connection. Do not overtighten — hand-snug plus a controlled wrench turn is sufficient to seat the threads without damaging the fitting.
