Hybrid Use:
• When metric tube fittings require assembly in alternate NPTF ports.
• Thread sizes 1/8” and 1/4” interchange without concern for torque with Camozzi’s patented Sprint and Compact seal-
ing system.
• For 3/8” and 1/2” threads, use caution, and consult hybrid torque specifications below.
Caution
: Mating material and female ports may be too soft for high torque values.
Check material hardness to avoid stripping, galling or cross-threading.
This table is ONLY a guide for "hybrid" situations that require interchanging thread types to accommodate tubing requirements.
