Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the joint seats and seals correctly within the drain circuit of your DCA-series generator.
• Direct-Fit Replacement — Replaces the original C0321200004 Drain Joint with no reworking of fittings or lines required; installs exactly as the factory component did.
• Broad DCA-Series Compatibility — Confirmed fitment across multiple DCA generator variants including DCA400SSV, DCA600SSV, DCA800SSK2, DCA180SSK, DCA250SSI, DCA1100SSC, DCA150SSK2, and more.
• Leak-Free Fluid Routing — A correctly functioning drain joint maintains a closed, sealed fluid path; a cracked or degraded joint can allow fluid to escape, leading to contamination, low fluid levels, and potential engine damage.
• Fluid System Safety — On diesel-powered generator sets, an intact drain joint is essential to preventing uncontrolled fluid release that could create fire risk or environmental hazard on the worksite.

The drain joint is a connector fitting within the fluid drain circuit of the generator, providing a secure, leak-free junction point where drain lines meet the engine or base frame drain system. It controls the flow path during routine fluid changes and maintains a sealed system during normal operation. When this fitting cracks, strips, or deteriorates, it can cause fluid seepage, making timely replacement critical to maintaining both the cleanliness and safety of the generator set.
