Inlet and Bearing Swivels

Introduction to our Swivels

Harlsan RC Drilling Inlet & Bearing Swivels are made to the high standard demanded by the reverse circulation drilling industry. We have years of experience in precision manufacturing that ensures the quality of every Harlsan RC Swivel is built up to this uncompromising standard.

If you need a Top Inlet, Bottom Inlet or Bearing Swivel for a new or existing rig Harlsan Swivels will improve performance and reduce your downtime. Feedback from our customers is that Harlsan Swivels consistently drill longer between reseals. We have adapter flanges & plates to suit your rig.


“The Harlsan Bottom Inlet Swivel handles higher pressure and the ease of field servicing has dramatically reduced our down time. With the sealing system we are consistently drilling longer between resealing.”

Jaimie Seed; Challenge Drilling

If you are drilling deep RC holes the Harlsan 4’’ & 4 ½’’ Bottom Inlet Swivels are designed and engineered to handle the high air pressure required for these drilling operations.
