We offer three brands: N8200C Generic, N8201C Sigma, & N8202C Conti (the 10" & 12" sizes will not interchange, ie. NL8202 Blucor must be used with N8202C couplings in 10" & 12"). They are installed over the cover of the hose to permit full flow of materials with no turbulence and also prevent coupling "wear out" with abrasive products. They come complete with plated nuts and bolts (N298NT- & N298BT-) and can be attached in the field. Gaskets are sold separately, but sometimes are not required if the end of the hose is cut squarely to actually work as a seal (flanges to be set back 1/4-3/8" from the end of the hose). An installation video is available.

Warning: <<Ensure the hose is physically compatible with this brand
