Abstract: An attenuator for high pressure fluid systems includes a shielding stud including first and second ends and a cylindrical space extending therebetween. The attenuator comprises a cylindrical, attenuator body disposed within the cylindrical space and defining a pressure chamber therein. First and second seal heads are positioned within first and second ends of said shielding stud and coupled to the attenuator body using a tensioner assembly and a plug threadingly coupled to first and second inner threaded surfaces of the shielding stud in first and second ends thereof.

Abstract: An attenuator for high pressure fluid systems is provided. The attenuator includes a shielding stud including first and second ends, a cylindrical space extending therebetween, and a housing fixedly coupled to the first end. The attenuator includes a body disposed within the cylindrical space and defining a pressure chamber therein. The body includes an engaging wall extending axially beyond an opening to the pressure chamber and defines a sealing chamber therein. A seal head positioned within the sealing chamber is coupled to the body using a tensioner assembly coupled to the engaging wall. The seal head is engaged with the body first end to define a seal therebetween and an end cap is coupled to the second end of the shielding stud and the seal head. The end cap can apply a compressive force to the seal head to compress the seal head against the body and apply a tensile load to the shielding stud.
