These Low Pressure Unions are available in a variety of polymers, providing several lowcost and chemically-resistant options. The union assemblies below include fittings as shown in the table. The unions in the right column do not include fittings, allowing for customizing the fitting selection. In some cases, a union can be configured to connect two different tubing sizes, for example, if 1/4-28 Flangeless fittings for 1/16” and 1/8” OD tubing were selected, they can be used with the P-603 union to connect the two different tubing sizes.
