These machined adapters connect pressure gauges, transmitters and water meters to equipment with a different port size or thread. Brass and 304 stainless steel constructions suit water, air, oil and other fluids compatible with the selected material. Hexagonal bodies provide wrench access during installation.
Brass options include male-to-female, male-to-male, female-to-female and reducer-bushing forms. The 304 stainless steel range provides female-to-male conversions based on M14×1.5 and M20×1.5 female connections.
| Parameter | Brass range | 304 stainless steel range |
|---|---|---|
| Material | Brass | 304 stainless steel |
| Connection forms | Male × female, male × male, female × female, reducer bushing | Female × male |
| Metric sizes | M14×1.5 and M20×1.5 | M10×1, M14×1.5 and M20×1.5, according to conversion |
| Inch sizes | 1/2in configurations; specify the thread standard | 1/8in, 1/4in, 3/8in and 1/2in configurations; specify NPT or BSP as required |
| Manufacturing | Precision-machined threads and reinforced wall construction | CNC-machined body and threads |
| Female instrument connection | Male connection choices | Reference length |
|---|---|---|
| M14×1.5 | 1/2in NPT; 3/8in; 1/8in; M10×1; M20×1.5 | 22mm |
| M20×1.5 | 3/8in; M14×1.5; 1/8in; 1/4in NPT; M10×1 | 25mm |
For the 3/8in and 1/8in choices, specify the required thread standard when ordering. Inch-thread pitch options include 14, 19 and 28 threads per inch across the range; metric options use 1mm or 1.5mm pitch. Available combinations depend on the selected adapter. Confirm the dimensions of the exact conversion, particularly where installation clearance is limited.
Specify the material, female and male connection sizes, thread standard and sealing arrangement. Custom thread dimensions are available. Match the complete adapter to the medium, working pressure and temperature of the installation.
Align the mating threads carefully and apply the sealing method appropriate to the connection. Use the hexagonal body for tightening and verify the completed connection before putting the pressure system into service.
