Tecumseh k30-6 Rotolock Adapter Kit Ag Av Compressors

Product Description

The TECUMSEH k30-6 is a rotolock adapter kit designed to facilitate leak-free sweat connections on AG and AV series hermetic compressors. Rotolock adapters convert the threaded rotolock valve port on the compressor to a copper sweat fitting, allowing field tubing to be brazed directly to the adapter. This kit covers both the suction and discharge connections, accommodating a 1/2 inch inner diameter and a 7/8 inch inner diameter sweat interface. HVAC-R technicians and refrigeration mechanics install this hardware during compressor replacement or system commissioning where rotolock-to-sweat transitions are required.

This adapter kit is intended for use with TECUMSEH AG and AV series hermetic compressors in light commercial and residential refrigeration and air conditioning applications. It is commonly installed during compressor changeouts when the existing line set terminates in sweat copper tubing and the replacement compressor uses rotolock valve ports. The dual-size configuration of this kit addresses both the suction side and discharge side of the compressor in a single package, reducing the need for separate fittings sourced from multiple suppliers.

Key Features

• Converts rotolock compressor ports to sweat copper connections for field brazing
• Covers 1/2 inch ID and 7/8 inch ID sweat sizes in one kit
• Designed for TECUMSEH AG and AV series hermetic compressors
• Supports standard refrigeration and air conditioning tubing practices
• Simplifies compressor replacement where rotolock-to-sweat transitions are needed

Compatibility

Designed for use with TECUMSEH AG and AV series hermetic compressors equipped with rotolock valve ports requiring 1/2 inch ID and 7/8 inch ID sweat connections.

Installation Notes

Installation should be performed by a certified HVAC-R technician or refrigeration mechanic holding the appropriate EPA Section 608 certification. Recover all refrigerant and depressurize the system before removing any rotolock fittings or performing brazing work. Use nitrogen purge during brazing to prevent oxide scale formation inside the refrigerant circuit. Torque rotolock nuts to compressor manufacturer specifications and pressure-test the system before recharging.
