Stainless Steel Forged NPT Threaded Male Adapter Tube Fittings
**Product Features**
1. Twin ferrule fittings provide metal-to-metal seal connections, non-elastomeric seals for leak-free connections.
2. Designed to have a maximum allowable working pressure higher than that of any tubing.
3. Stainless steel tube hardness: the hardness of the tube shall be not greater than 85 HRB.
4. Available in sizes from 1/16 to 2 inches and 2 mm to 50 mm.
5. Fittings materials include 316 stainless steel, steel, brass, aluminum, nickel-copper, Hastelloy C, 6Mo, Incoloy 625, and 825.
6. Special treated back ferrule for enhanced security.
7. Silver coated threads to reduce galling.

9. Industry standard design for all instrumentation grade tubing.
**Product Performance**
1. Hydraulic proof pressure test (1.5 times the maximum permissible working pressure): no leakage.
2. Dismantling and reassembly test (dismantle ten times): no leakage.
3. Vacuum test (1 × 10−4 mbar or greater): leak rate less than 1 × 10−8.
4. Maximum static gas pressure test (with nitrogen gas to 150% of pressure rating): no visible bubbles.
5. Hydraulic impulse and vibration test (pressure impulses between 0.5 Hz and 1.7 Hz, vibration between 23 Hz and 47 Hz): no leakage.
6. Thermal cycle test (ambient to +80 °C and then to -25 °C with hydrostatic pressure): no evidence of leakage.
7. Pneumatic pressure vibration test (frequency set at 45 Hz, 20 × 106 cycles): no failure.
8. Fire test (in accordance with BS ISO 19921): no leakage.
9. Corrosion resistance test (exposure for at least 168 hours): no visible corrosion.
10. Deep water submersion test (equivalent to 3048 m of seawater): no helium detected.
11. Minimum hydrostatic pressure test (four times the maximum permissible ambient pressure rating): no leakage.
