Copeland 998-0034-09 Adapter Kit

When the Rotalock valve on the compressor doesn't match the stub tube you're sweating in, this is the fitting that closes the gap. The Copeland 998-0034-09 converts a 1-1/4"-12 Rotalock thread down to a 1-1/8" I.D. stub tube, so you can land your suction or liquid line without cutting into the compressor's factory valve body or bodging a field-fab coupling that'll leak by next season.

This is the genuine OEM Copeland kit - solid brass adapter body with machined threads that seat clean on the first try, not a soft-metal knockoff that strips out after a couple of service calls. It ships complete with the Rotalock seal ring, so you're not scrambling to find a compatible O-ring at 4pm on a Friday rack call.

Key Benefits

• Correct Thread Interface: 1-1/4"-12 Rotalock thread mates directly to the compressor's factory valve, no adapters-on-adapters.
• 1-1/8" Stub Tube I.D.: Sized for standard 1-1/8" O.D. copper suction/liquid lines, ready for a straight solder joint.
• Seal Included: Comes with the Rotalock gasket/seal ring needed for a pressure-tight connection, nothing extra to source.
• OEM Brass Construction: Machined brass body holds up to repeated service disconnects better than cast or pot-metal aftermarket adapters.

Common Questions

• Does this include the seal? Yes - the 998-0034-09 kit comes with the Rotalock seal ring needed to make the connection pressure-tight.
• Will this fit a non-Copeland compressor? If the valve uses a matching 1-1/4"-12 male Rotalock thread, this adapter will seat and seal regardless of compressor brand.
• Is this the right adapter for my compressor? Match it by valve thread size and stub tube I.D., not by compressor model - Copeland uses this 998-0034 family across multiple compressor lines with different valve sizes, so confirm both dimensions on your unit before ordering.
