ISO Tees
ISO-K tees
All three ports on a standard ISO tee share one flange size. The tee is built around a straight main tube with a single side port at 90 degrees. This allows for the integration of a gauge, valve, vent, or second pumping line along the main line.

ISO reducer tees and ISO-to-KF reducer tees
A reducer tee changes size at the branch so a larger line can feed a smaller instrument or valve port. The ISO-K Reducer Tee keeps all three ports in the ISO family, with ISO 80 to ISO 200 main lines and ISO 63 to ISO 160 branches. The ISO-K to KF (ISO-QF) Reducer Tee runs an ISO 63, 80, or 100 line with a KF40 or KF50 branch, combining an ISO-to-KF adapter and a junction in one part. For full KF layouts, see KF Tees.
Complete the ISO connection
Each port on an ISO-K tee needs a centering ring, O-ring, and clamps. Order claw clamps and bolt rings from ISO Clamps & Fasteners and centering rings and O-rings from ISO Hardware & Seals. To finish the line, add ISO Flanges, ISO Nipples, ISO Elbows, ISO Crosses, or ISO Bellows & Flexible Hose where the system needs movement.
