HOKE® Precision Instrument Pipe Fittings are manufactured with reduced tolerance NPT tapered threads in a wide variety of configurations to provide broad application capabilities.

Ratings and specifications are as follows:

Threads utilised on HOKE® Precision Instrument Pipe Fittings are National Pipe Taper (NPT) which exceed the requirements of ANSI B1.20.1.

Pressure Ratings for temperatures up to 38°C (100°F) are identified for each individual pipe fitting in the dimensional data charts.

Temperatures noted below apply to basic fitting capabilities. In all cases consideration must also be given to the type of thread sealant used. For example, PTFE tape has a maximum temperature rating of 232°C (450°F).

316 Stainless Steel:  -198 to 648°C (-325 to 1200°F) Note: Prolonged exposure to temperature over 426°C (800°F) is not recommended.
Brass:  -198 to 204°C (-325 to 400°F)

Materials: HOKE® Precision Instrument Pipe Fittings are available as standard in Brass and 316 Stainless Steel. HOKE® Pipe Fittings can also be supplied in other materials including Monel®, Hastelloy® C276, Inconel®, Incoloy®, Duplex, Super Duplex and Titanium, as well and in special shapes. Specifications for standard materials are:

316 Stainless Steel Forgings: ASTM A-182
316 Stainless Steel Bar Stock: ASTM A-479
Brass Forgings, Alloy 377: QQ-B-626
Brass Bar Stock, Alloy 353: ASTM B-453
or Alloy 360: QQ-B-626

Heat Traceability: HOKE® Precision Instrument Pipe Fittings are heat code traceable in all alloys except brass with certified material test reports (CMTR’s) available on request.

Monel, Hastelloy, Inconel and Incoloy are registered trademarks.
