assembled into female NPTF ports)
“Hybrid” Torque Specifications - (Pro-Fit® - NPTF Fittings
assembled into female BSP ports)
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.

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 sealing system.
• For 3/8” and 1/2” threads, use caution, and consult hybrid torque
specifications below.
Hybrid Use:
• When inch OD tube fittings require assembly in alternate BSP ports.
• Thread sizes 1/8”, 1/4”, and 3/8” interchange without concern for torque with
Camozzi’s patented Pro-Fit® Thread sealing system.
• For 1/2” threads, use caution, and consult hybrid torque specifications below.
