90° Elbows, PTFE-Lined

PTFE - PN 10 (015-125 & 600)
PTFE - PN 10 (150-500)
PTFE - PN 25

Material - Steel
1.1 PTFE - Paste, white, ASTM D-4895
1.2 PTFE - Paste, static dissipative, ASTM D-4895
2.1 St 37.0 = 1.0254 / 1.0038, DIN 2605
2.2 St 35.8.1 = 1.0305, DIN 2605
3.1 RSt 37-2 = 1.0038, DIN 2632

For "BC" & "G" in part no substitute:

BC = 41 for 2 fixed flanges
BC = 40 for 1 fixed flange, 1 lap joint flange
BC = 42 for 2 lap joint flanges
G = 1 for paste PTFE virgin white
G = 3 for paste PTFE static dissipative
