Accessories and Ordering
Specify BDM-17 size, body material, actual thread standard and size, inner and outer sheath diameters, armor construction and required ring orientation. Include the required Ex application and operating temperature configuration.
For lead-sheathed cables, specify the earth tag and earth plug described for that application. Nylon washers and locknuts are standard except for NPT versions. PVC shrouds, serrated washers, red fibre washers and A/B putty compound are listed as optional accessories.
For a barrier configuration, specify the compatible compound system and its supply with the order. The supplied data does not define the compound formulation, curing procedure or installation torque; use the documentation for the delivered configuration.
