Stopping Plugs are used to close unsed entry holes in an apparatus. These plugs are mainly manufactured out of brass but can be supplied in SS-304/316 and Aluminium also. Brass plugs are nikel plated to avoid corrosion whilst storage and use. These are supplied with "O" Rings for IP Protection. These Plugs are Certified by Central Institute of Mining and Fuel Research, Dhanbad for use in Weather proof as well as Flame proof conditions.
Suffix - BSP = for Brass Plugs, SSP = for SS Plugs and ALSP = for Aluminium Plugs. Threads can be ET/mm/NPT as per requirement.
