Danfoss (Weatherhead)

Steel Pipe O-Ring

Typical Application: Grease, instrumentation and most hydraulic systems.
Pressure: Refer to the pressure charts above. The maximum working pressure of an adapter is the lower working pressure of the end size. Ex: C3069x8x6, 8 = 4000 psi and 6 = 5000 psi. Maximum working pressure is 4000 psi.
Vibration: Fair resistance.
Temperature Range: –65°F to +400°F.
Material: Carbon Steel – AISI/SAE 12L14, Stainless Steel – type 316 Plating – Zinc, yellow dichromate finish ASTM B633 Type II.
Used With: Brass, bronze and iron pipe.
Advantages:
Dryseal pipe threads (NPTF) (SAE J476), zinc
plate, compact size. Broad range of sizes and styles.

Material: Buna-N, 90 Durometer Temperature Range: –40°F to +250°F (–40°C +121°C) Standard O-ring complies with SAE specification SAE J515 Type1.

Assembly Instructions 1. Tighten approximately 2-1/2 turns past hand tight. 2. Welding procedure: Use electric weldrod AWS-E7018. Recommended procedure specifies using lower amperage than usual and puddling of molten metal to permit gasses created by lead in steel to work through molten lead deposit. Label Set: FS-2000 (adhesive).
