Parker SH2C Pneumatic Hose Coupling Nipple 1/4 in Industrial

Product Description

The PARKER SH2C is a pneumatic hose coupling nipple designed for industrial compressed-air and fluid-transfer systems. This coupling features a male NPTF threaded connection in a 1/4-18 thread size, a 1/4-inch body diameter, and a stainless steel construction finished with zinc chromate. It is rated for a maximum working pressure of 300 psi, making it suitable for demanding shop-air and light industrial pneumatic circuits. At 1.66 inches in overall length, the SH2C is a compact, durable nipple intended for use wherever an Industrial Interchange-style quick-disconnect fitting is required. Pneumatic technicians and maintenance professionals install this part in production, MRO, and service environments.

The SH2C fits Industrial Interchange pneumatic quick-disconnect systems, which are among the most widely used coupling standards in North American shop-air and production-line applications. It is well suited for residential and commercial maintenance shops, manufacturing facilities, and field-service rigs where stainless steel corrosion resistance is required. The male NPTF thread seals on the thread form itself, reducing the risk of air leaks in threaded connections. This coupling is typically installed on air hoses, manifolds, or equipment ports that accept 1/4-inch Industrial Interchange nipples.

Key Features

• Industrial Interchange coupling type for broad compatibility with standard quick-disconnect bodies
• Male NPTF threaded connection in 1/4-18 thread size for reliable pressure sealing
• Stainless steel construction with zinc chromate finish for corrosion resistance in demanding environments
• 300 psi maximum working pressure rating suitable for typical shop-air and industrial pneumatic circuits
• Compact 1.66-inch overall length with 0.56-inch hex for standard wrench installation

Compatibility

Designed as an OEM-style replacement nipple for Industrial Interchange pneumatic quick-disconnect systems accepting a 1/4-inch body diameter male NPTF nipple.

Installation Notes

Pneumatic technicians and maintenance professionals install this fitting. Always depressurize and bleed the pneumatic line completely before removing or installing any coupling. Apply thread sealant appropriate for NPTF threads per the system requirements and applicable facility or code standards. Use a properly sized wrench on the hex flat and avoid over-tightening, which can damage the thread form or seat.
