Champion Quick-Lock Stem and Reducing Adapter (14mm to 63mm)

Adapters are the parts that keep a Champion Quick-Lock job moving when the sizes do not line up. Two families live here, and they do different jobs.

• Reducing stem adapters step a fitting down a size. The large end plugs into a Quick-Lock fitting body, the small end accepts the next size down of tube. Use one when a 50mm main has to continue as 32mm, or when you want a 25mm branch out of a 40mm tee without buying a reducing tee.
• Stem adapters put a plain calibrated stem on a thread or on small-bore tubing. The stem pushes into any Quick-Lock union, elbow or tee of that size, so an NPT source can feed a fitting body directly.

Champion catalogs a 32mm to 20mm reducing stem adapter, printed in the current price list as part number XCQL-RA-30-20, with no list price published. It is not shown above because we will not invent a price for it. Call or email and we will get a firm price and lead time from the factory.

Shared Technical Specifications

Installation and Torque

The stem end of an adapter is inserted into a Quick-Lock fitting body exactly as a length of tube would be, and the receiving fitting is torqued to its own published figure for that size: 300 cN.m (26 in-lb) on 20mm and 25mm, 400 cN.m (35 in-lb) on 32mm, 650 cN.m (58 in-lb) on 40mm, and 65 N.m (48 ft-lb) on 50mm and 63mm. 14mm is push lock and needs no torque. On the NPT side, use PTFE tape or a liquid sealant rated for compressed air.

Use a male threaded connector when you are going directly from a thread to a length of tube, since it has the push fitting built in, and a stem adapter when you need to feed an existing fitting body such as one leg of a tee or an elbow. The range reduces across more than one step, for example 40mm to 20mm and 63mm to 40mm, but it does not go 63mm straight to 20mm; chain two adapters only if there is no other way, because a reducing tee or a smaller branch run is usually better. Reduce only where demand downstream genuinely drops, since flow capacity falls off fast with diameter: at 125 PSIG Champion rates 63mm at 881 CFM, 40mm at 266 CFM and 20mm at 36 CFM over 100 ft. Adapters are reusable: loosen the receiving fitting's compression nut one to one and a half turns, push in, pull out, and inspect the o-ring before it goes back into service.

Ideal Applications

Stepping a main down as it travels away from the compressor and the demand falls off, branching a smaller drop out of a large tee, feeding a Quick-Lock fitting from a threaded source such as a dryer outlet or a receiver port, adapting 14mm runs down to 1/4 in or 3/8 in tubing at a bench or a machine, and finishing retrofits where the original installer left you a size you did not plan for.
