Default 2000 Air Conditioning Recharge - Coupler Question

I did see some references similar to this topic, so excuse me in advance if it is repetitive.

I'm pretty comfortable charging (adding freon), as my 2003 Cabby and 2004 A4 were simple and quick.

What size guage coupler is needed for the TT and where can it be purchased??? The one for the Cabby and A4 is too small. That is to you can connect your recharge hose to the L tube.

I have searched Google and YouTube and most are great but they don't address the TT.

Thanks for your response.

R=134 connections are universal. The Discharge Line uses the larger connection and the Suction Line uses the smaller port. If you are using a proper set of gauges, hoses & couplings, The discharge line has a red hose and the suction lime has a blue hose.

MK 1 TT's have both ports available. Some Audi's only had a coupler on the Discharge line.
