Elbolet has the similar appearance with latrolet, but is mainly used on 90 degree long radius elbows for thermowell and instrumentation connections. It is a self reinforced branch connection pipe fitting that available in buttweld end, socket weld end and threaded end, it can replace the reducing tee, reinforce plate and reinforced pipe. Buttweld elbolet is more and more popular in high temperature and pressure large diameter and thick wall pipe systems. The body of elbolets is made in excellent forgings, the material is best same as pipe’s. We supply carbon steel, stainless steel, alloy steel branch outlet pipe fittings for customized sizes.

Through elbolet and latrolet are very similar in exterior, but they are applied in different applications. Latrolet is used for taking branch which is not at 90 degrees to run pipe, it comes in a 45 degree or any other special degree as required by purchaser. While elbolet is used for 90 degree elbows to provide branch.
