Upchurch Scientific® Large Bore Unions from IDEX Health & Science allow you to use any 5/16-24 fitting and the appropriate ferrule to create a true zero dead volume connection with the P-134 Union

The U-658 Union is designed to be used with standard 1/2-20 flat-bottom threaded nuts and ferrules. Upchurch Scientific® PEEK™ Bulkhead Unions from IDEX Health & Science are designed to thread directly through your equipment housing to connect internal tubing to the outside. For use with standard 10-32 coned, 1/4-28 or M6 flat-bottom threaded fittings, each union has unique 3/8-24 external threads and comes complete with a stainless steel nut and lock washer to hold it in place. Note: Requires a 3/8 in. hole to mount. The recommended torque limit for these unions is 15 in. lbs (1.7 Nm).

Manufactured from PEEK™, ETFE, Delrin®, polypropylene or PCTFE, Upchurch Scientific® Low Pressure Unions from IDEX Health & Science provide offer low-cost and chemically-resistant options for lower pressure applications. Available with 1/4-28, M6 or 10-32 flat bottom threaded ports, these Unions can be configured to connect two different tubing sizes. Note: Actual pressure rating depends on selected fitting.

Upchurch Scientific® PEEK™ Zero Dead Volume Union Assemblies from IDEX Health & Science come complete with two Upchurch Scientific F-300 Fingertight Fittings for 1/16” OD tubing, and are pressure rated to 5,000 psi (344 bar). Also available are the Union bodies, shipped without fittings, to allow the easy use of the Upchurch Scientific Fingertight fittings of your choice.

Upchurch Scientific® Column Couplers manufactured by IDEX Health & Science are universal couplers that permit a low swept volume connection with minimal loss in column efficiency. These couplers will connect most columns with 10-32 internal threads to a precolumn filter or guard column with the same threads. They may also be used to join two columns in series. Available as either a single piece that makes coupling columns to guard columns or precolumn filters easy and hassle-free, or as a traditional couplers that consists of two Upchurch Scientific Fingertight fittings and a short length of 1/16 in. OD tubing - an excellent option for reducing overall flow path volume while coupling two devices together reliably.
