Precision Hose & Expansion Joints manufactures to the highest quality standards in the industry. All metal expansion joints and bellows are 100% tested either by hydro, pneumatic, liquid penetrant, or mass spectrometer. We can offer additional tests, if required, such as cycle life, burst test, ultrasonic, chemical analysis, radiography, shock and vibration, and Charpy impact testing.
Precision Hose & Expansion Joints continually strives for better products and to improve the efficiency of our service without compromising standards. These product and quality improvements are from the standard catalog item to the more complicated aerospace product lines. Precision Hose & Expansion Joints designs all metal expansion joints and bellows to EJMA, ASME B31.1, ASME B31.3 and ASME section 8.
Our expansion joints are manufactured to the highest quality standards in the industry.
