Midland Industries SSC32012 Ferrule Set 3/4 in 316SS

Product Description

The MIDLAND INDUSTRIES SSC32012 is a Mid-Lok compression ferrule set designed for 3/4-inch tube connections in high-pressure instrumentation systems. Constructed from 316 stainless steel, this two-piece ferrule set forms a leak-tight mechanical seal when paired with a compatible Mid-Lok body and nut. It is rated for a temperature range of -325 to 1200 degrees F and delivers allowable working pressures from 2436 psig at 0.049-inch tube wall thickness up to 5785 psig at 0.109-inch wall thickness, making it suitable for demanding process and instrumentation applications. Licensed plumbers and instrumentation technicians install this type of fitting.

This ferrule set is used in process control, instrumentation, and fluid handling systems where reliable tube-to-fitting connections under high pressure and wide temperature swings are required. It is compatible with 304SS or 316SS seamless tubing conforming to ASTM A269-04 or equivalent, with pressure ratings based on an ultimate tensile strength of 75000 psi and an allowable stress of 20000 psi per ASTM B31.3-2002. Typical install environments include industrial process lines, chemical handling skids, and instrumentation manifolds in both commercial and industrial settings.

Compatibility

Designed for use with Mid-Lok SS instrumentation fitting bodies and nuts in the N0320 Series. Compatible with 304SS or 316SS seamless tubing conforming to ASTM A269-04 or equivalent, for 3/4-inch tube outer diameter connections.

Installation Notes

Installation should be performed by a qualified instrumentation technician or licensed pipefitter in accordance with ASME B31.3 process piping requirements. Depressurize and isolate the system completely before disassembly or fitting installation. Do not overtighten the compression nut; follow the manufacturer-recommended turn count method standard for compression fittings. Verify tube end is cut square, deburred, and free of contamination before inserting into the fitting body.
