Typical applications for Lokring fittings include, but are not limited to, the following locations:
1. Branch pipe tee connection — 1 each 1 1/4 in. If the car is equipped with a brake pipe reduction device, it willrequire a second tee connection.
2. Control valves — 3 each 3/4 in. flange couplings, may be straight or 90°, depending on brake cylinder design.Also some cars are equipped with an extra reservoir and would require an extra coupling.
3. Combined reservoirs — 2 each 3/4 in. flange couplings, may be straight or 90°, depending on brake cylinderdesign. Also some cars are equipped with an extra reservoir and require an extra coupling.
4. Retaining valve — 1 each 3/8 in. flange.5. Brake cylinders — 1 each 1/2 or 3/8 in. flange with or without a brake cylinder measurement tap opening.
5. Empty/load equipment which will require a flange for each valve connected, between 4 and 6 each 1/2 or3/8 in. Straight couplings for train line 1 1/4 in.
