Designed for service work on older Purex equipment, this component helps restore the fit, seal, or mechanical function that keeps the system operating correctly. The threaded nipple is used on CF/SMBW 800 1/4" Nipple applications and supports a secure plumbing or relief connection in the equipment assembly. It is a useful replacement when the existing part is cracked, corroded, stripped, distorted, leaking, missing, or no longer holding the correct operating position.Accurate replacement parts are important on legacy systems because small differences in diameter, thread style, or mounting geometry can affect sealing and alignment. This part is best suited for precise repairs where the matching OEM-style part number, 71389, is the main guide for compatibility. Use the part number to verify fit before ordering, especially on legacy equipment with possible model-year or revision differences.
