Swagelok SS-400-3 is a 316 stainless steel union tee for 1/4 in. tube OD tubing, delivering a three-port, T-shaped connection in a compact Swagelok tube-fitting assembly. The 316SS body provides corrosion resistance and is designed for reliable, leak-tight seals when paired with Swagelok nuts and ferrules on 1/4 in. tubing. This base model also has variants in the SS-400-3 family, including SS-400-3JA with SilcoNert coating and SS-400-3BT bored-through union tee, offering options for coated or through-bore designs while maintaining the same 1/4 in. tubing interface.
