PRESSURE FITTINGS

One of the common pressure fitting threads in the industry is NPT (National Pipe Thread), with 1/2" NPT being a very common size.

NPT threads are slightly tapered by 1/16" over their length ( 3/4" taper per foot)and are usually used with PTFE thread sealing tape.

Common size range : 1/8", 1/4" 3/8", 1/2", 3/4", 1", 1 1/4", and 1 1/2"

PRESSURE FITTINGS

Hydraulic connections.

Snaptite Connections are used on all hydraulic oil connections, such as the hydraulic BOP's and the power pack to reel pack connections.

Care should be taken to bleed off trapped pressure before releasing or connecting these fittings.

Huber Connections

These are used on high pressure

grease connections such as on the

supply and return drain hoses on the

Grease Injection Head (GIH) and

Grease Injection Unit (GIU).

Pneumatic (Air) Connections

The most common is the "Chicago" type, which has a bayonet type twist connection.

For safety a locking pin is inserted to prevent the connection twisting open.

A safety cable connects the two hoses to constrain their movement in the event that they separate under pressure.
