scope:

A snubber covered by this specification is a pressure transmission device which restricts the rate of fluid flow to a pressure sensing instrument and, as a result the rate of pressure change.

Snubbers covered by this specification shall be classified according to the following:

1 - L - a - P - G Type Class Composition End Cleanliness (see (see (see 1.2.3) connection (see 1.2.5) 1.2.1) 1.2.2) (see 1.2.4)

The type of service in which the snubber will be used shall be designated by one of the following numbers:

Type Service 1 Oil above 225 saybolt universal seconds (SUS) at operating temperatures. 2 Gasoline, fresh water, steam, light oils below 225 SUS. 3 Gases 4 Seawater (composition b only)

Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, Naval Sea Systems Command, SEA 55Z3, Department of the Navy, Washington, DC 20362-5101 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

The range of operating pressures shall be designated by the following letters:

Class Operating pressure range L 10 to 1000 pounds per square inch gauge (lb/in²) H 1001 to 6000 lb/in²

The material composition of the snubber shall be designated by one of the following letters:

Composition Material a Copper nickel alloy b Nickel-copper (monel) alloy c Corrosion resisting steel

The configuration for the snubbers end connection shall be designated by one of the following letters (see 3.3.2):

End connection Application P Pressure gauge general applications (see 3.3.2.1.1). T Pressure transducer general applications (see 3.3.2.1.2). O Pressure gauge oxygen applications (see 3.3.2.2.1). S Other applications (see 6.1.1.3). The end connections must be specified in the contract ordering data.

The method for cleaning the snubber shall be designated by one of the following letters:

Cleanliness Application G General applications X Oxygen and dry nitrogen applications
