Nozzle Sets

Apex Instruments has a large selection of button-hook nozzles in multiple materials. Determining the size needed for isokinetic sampling depends on the stack gas velocity. Determining the material depends on the stack temperature and the sampling method. We provide technical support and can help with configuration.

Unique to Apex Instruments, the stainless steel nozzle shank has integrated ferrule with O-ring groove. The most popular nozzles are constructed from seamless 316 stainless steel and can be coated with FEP or SilcoNert®. Standard sampling nozzles are 4 inches long and have a 5/8-inch outer diameter shank for attaching to the probe union. Other sizes and configurations are available. Nozzles must be measured/calibrated before initial use. Other nozzle materials include PTFE-lined, Inconel, borosilicate glass, and quartz.

To meet your special needs we offer a variety of individual nozzles in different sizes and materials (sizes are based on 1/32 inch increments) up to 2 inches in diameter. Please call us for availability and pricing on additional nozzles.

For nozzle sets with additional features, use the Part Number Configuration Legend and have your custom part number ready when you contact an Apex Instruments sales representative.
