Bunn 54281 Elbow Barb Fitting 0.38 X 0.188 Inch Ppsu

Product Description

The BUNN 54281 is a polyphenylsulfone (PPSU) elbow barb fitting designed for use in BUNN commercial beverage equipment fluid systems. It connects tubing at a 90-degree angle, with a 0.38-inch barb on one end and a 0.188-inch barb on the other. PPSU is a high-performance thermoplastic rated for elevated temperatures and repeated sterilization cycles, making it well-suited for hot-water and beverage-dispensing circuits. Technicians replacing cracked, leaking, or failed fittings in BUNN equipment will find this an exact OEM-specification part.

This fitting is used in BUNN commercial appliance plumbing circuits where tubing transitions in direction and where two different barb diameters must be joined. Typical install scenarios include hot-water dispensers, coffee brewers, and similar foodservice equipment that route flexible tubing through tight chassis cavities. The reducing elbow geometry allows routing around obstructions while accommodating mismatched tubing sizes in a single fitting.

Key Features

• PPSU construction withstands high-temperature water and repeated sanitation cycles
• 0.38-inch barb to 0.188-inch barb reducing elbow geometry joins two different tubing sizes
• 90-degree elbow profile simplifies routing in space-constrained equipment interiors
• OEM BUNN part number ensures dimensional and material compliance with original design

Compatibility

Designed as an OEM-style replacement fitting for BUNN commercial appliance fluid systems requiring a 0.38-inch by 0.188-inch barb elbow connection.

Installation Notes

Installation should be performed by a qualified commercial appliance technician or plumber familiar with BUNN equipment. Disconnect and lock out power and shut off the water supply to the unit before disassembling any plumbing connections. Ensure tubing is fully seated past each barb bead and secured with the appropriate clamp to prevent leaks under operating pressure. Follow all applicable local plumbing and foodservice equipment codes when servicing commercial beverage equipment.
