Perlite elbows are made of expanded perlite, a high temperature, hydrophobic insulation that is corrosion and moisture-resistant. Perlite elbows are designed to fit various pipe sizes and can be used in applications with temperature ranges from ambient up to 1200°F. Perlite elbows can be fabricated as Long Radius (LR), Short Radius (SR), or Socket Weld (SW) in 90 and 45 degree angles. View our selection of perlite elbows by type below!
