The Legris company produces the 90 degree elbows or "Legris elbows" that are used to build the proton pack. They are used, essentially, to connect the different colored hoses you see on the Proton Pack to another area on the pack where the other end of the hose leads to. The Legris elbows used on the Proton Pack are all the same type and size, and appear throughout the overall pack, to connect the hoses. In some instances, you can see, from the reference photos, that one end of a hose connects to a legris elbow, and the other end connects to a brass fitting. The brass fittings are made by Legris and are known as "straight male connectors". The 5/32 hose fits into them, just like they fit into the Legris elbows.
They are mentioned here because of the interconnected nature of the Legris elbows, to the hoses, to the brass fitting. In addition to the brass fittings, the mention of the hoses is essential to understanding where the Legris elbows are located and what size they are. The hoses coming out of all of the Legris elbows are 5/32 fractional inch size, and so is the size of the Legris elbows. The other side of the elbow has a 1/4 or 1/8 inch thread or NPT, which is made of brass or steel. In the Legris catalog, the part number is 3109 desribed as: male elbow- fractional inch tube to NPTF and the type used on the Proton Pack is on page F6. this is noted because under the part number 3109 there are different variations, but all of them will look close enough and fit the 5/32 hose. Look at the reference photos and you will know what you will need.
The brass fitting is also located on page F6 of the Legris catalog and is part number 3175, described as : straight male connector- fractional inch tube to NPTF. The 1/4 or 1/8 size can be used because it is just glued into the proton pack and isn't exposed anyway. The catalog invites users to : Get connected with Legris on the American market at www.legris.com Legris is a european company with branches all over the world. The main headquarters is in Paris, France. Legris is pronounced: [lay-gree] but vendors also hear it pronounced: [leg-griss]
