These 360 μm stainless steel unions with 50 µ bore are constructed from premium grade PEEK material to connect with PEEK or fused silica tubing at pressures up to 10,000 psi (or the maximum pressure for which the tubing is rated, whichever is lower).
The manual tightening tool (C360ET) is recommended for installing 360 micron fittings, which are easily overtightened when a standard wrench is used.
