Common Applications
The TKDDCG50 is a combination reservoir designed to thread directly onto Barrow 17W DDC-class pumps such as the SPB17 series. The body is a 50mm outside diameter acrylic tube with a POM cap, and the cap carries two G1/4 internal threads - typically one used as a fill port and one as a return inlet, with an internal anti-cyclone tube to keep the pump bowl flooded. Available lengths are 60mm, 90mm, 140mm, 190mm, and 240mm so the reservoir volume can be matched to the case clearance and the loop's air-bleed needs. The unit ships ready to screw onto a matching threaded 17W pump body and includes the O-rings required for the seal. Pump and fittings are sold separately.
Frequently Asked Questions
Q: Which pumps does this reservoir thread onto?
A: Barrow 17W DDC-class pumps with a threaded body, including the SPB17-S V2 and SPB17 V2 RGB. Generic DDC pumps without the Barrow thread pattern are not compatible.
Q: What lengths are offered?
A: 60mm, 90mm, 140mm, 190mm, and 240mm. Choose the longest length that still clears the case for the largest air-bleed volume.
Q: What thread, diameter, and material does it use?
A: 50mm outside diameter acrylic tube with a POM cap that carries two G1/4 female threaded ports. The seal between cap and pump is a captive O-ring.
Q: Are fittings included?
A: No. Two G1/4 ports on the cap accept any standard compression or rotary fitting; you supply the fittings and a stop plug or fill cap as needed.
Q: Does the reservoir come with a pump?
A: No. The TKDDCG50 is a reservoir only. A compatible Barrow 17W threaded DDC pump must be purchased separately.
