HAILEA HK-150A Hose Connector Spare Set Explained
This two-piece hose connector set is the spare that restores a leak-free seal on HAILEA HK-series chillers, covering the HK150a, HK300a, and HK500a. The connectors are where your chiller meets the tubing, and over time the threads and seals take wear from being fitted, removed, and flexed during maintenance. Each set contains two pieces, and you should confirm your exact chiller model against the original manual before ordering so the fittings match.
Chillers earn their keep in Singapore, where ambient temperatures sit at 27-29C and sensitive species, shrimp, and many marine setups need cooling that a fan alone cannot reliably deliver. Because the unit runs hard year-round, the hose connections are a common point for slow drips. We recommend checking these fittings at every chiller service, replacing worn connectors before a small weep becomes a puddle inside your cabinet.
