Solutions for Coiled Tubing applications

We deliver your solution


Designed for rugged-duty and high pressure well intervention - Our partner DSTI's rotary unions deliver reliable fluid transfer for coiled tubing applications such as cleanouts, circulation, hydraulic fracturing, acid stimulation, cementing, and drilling. 

Fracking & Drilling Mud Systems
Single flow passage swivel joints provide reliable fluid transfer needed for demanding fracking operations. Specialized seals capable of handling abrasive and corrosive media and a robust roller thrust/angular contact bearing combination system provide dependable performance - minimizing service and repair downtime. 

Service Reel Applications
Designed for high pressure hydraulic fluids, multiple flow passage rotary unions provide reliable fluid transfer needed for winding and releasing of continuous lengths of coiled tubing during workover, drilling and well completion operations. Our fluid products are trusted by leading CT equipment manufacturers and are currently in fields operating around the world.

Solutions for Crane Applications

We deliver your solution

The rotary joint in the crane provides the necessary power to perform the necessary movements and lifting of the crane, therefore the rotary transmission package is of very high importance.  
Penlink offers a wide range of solution, both hydraulic rotary unions and electrical slip rings. We can also integrate fiber optical channels and high accuracy encoder (slewing). 
We have a very wide range of ATEX, IECEx certified slip rings! We can also certify custom slip rings for small volume projects. If the crane operates in different zones or it needs to be an emergency use situation, we can offer combined solutions using two rotary joints. 

If requirements are needed for high data speeds, we can offer 1Gb/s data transfer in an electrical slip ring module. Our signal slip ring is sealed to make sure carbon dust from power rings doesn’t penetrate and disturb signal rings over time. 

We offer separated chambers in the slip ring due to new regulations in the industry!

Solutions for Flexible Moon Pool Drape Hoses

We deliver your solution


Trusted by leading oil and gas equipment manufacturers and operators, our HPI moon pool hose fluid swivels are utilized in topside and subsea applications where flexible hoses (jumpers) are susceptible to stress and torsion from equipment installation, production, ocean currents and other environment conditions. 

Unlike many competitors, Penlink's swivels allow drape hoses and other flexible hoses to rotate at low-torque, even at full operating pressures - extending hose service life, therefore saving time and money from unplanned repair and downtime. 

Penlink's swivels are engineered based on project application requirements and qualified to API 6A, 16C, and 17D. The compact design offers reduced weight with heavy-duty internal bearings to support hose loads and are operational for sour service in accordance with NACE MR1075.

  • Cement Lines
  • Managed Pressure Drilling (MPD)

Solutions for Subsea Flowline & Jumper Systems

We deliver your solution


Our subsea swivels allow relative rotation between flowline equipment and flowline pipe to maintain proper angular positioning during installation, therefore reducing installation time and eliminating bending moments to prevent equipment / pipe damage as subsea equipment is lowered to the sea floor. 

To date, our partner DSTI have manufactured, tested, qualified, and delivered nearly 200 subsea swivels - reliably installed and operating in field locations worldwide. 

Committed to the ever-changing challenges of offshore oil and gas development, we've made significant and ongoing investments including capacity manufacturing and custom pressure and load test equipment for testing products up to 55” [1400 mm] in diameter, bending loads up to 3 million ft-lbs [4100 kNm] and tensional loads up to 3.1 million lbf [13900 kN].



  • Metal-To-Metal Sealing System
  • Designs Suitable For High Temperature / High Pressure (HTHP) Applications
  • Designed To Be Operated by ROV
  • Specialized Bearing Design To Absorb Bending Moments & Loads
  • Torsion Resistance Solutions While Swivel Is Energized
  • Available In API Flange / Hub, Grayloc & Other Connections
  • Variety Of Materials To Meet Project Requirements

Solutions for Top Drive Applications

We deliver your solutions


Rotary Unions

We provide reliable fluid sealing and transfer solutions for hydraulic and abrasive service required by today’s demanding top drive drilling applications. We provide rotary union for water cooled motors.  

Our fluid swivel products designed for top drives remove much of the manual labour previously required on traditional rig floors - reducing risk and improving safety. We offer a variety of solutions for onshore and offshore top drive drilling systems including multiple flow passage swivels for independent pipe handling hydraulic lines used to reliably pick and place drill string.



We provide the world most rugged a reliable no-bearing, contactless magnetic encoder for Top Drive/Draw-works motors/system. XP5 SMARTSafe™ sensors power the world's first explosion-proof encoder with removable electronics and no external barrier!  

They are cULus, ATEX, AEx & IECEx certified and offer incredibly reliable no-bearing construction!  SMARTSafe XP5 sensors can be used in ATEX/IECEx, cUL, AEX, and UL gas hazardous environments.

Solutions for Umbilical Winch Systems

We deliver your solution

We provide fluid sealing solutions and optical / electrical slip rings for umbilical hose reel applications designed to provide operational flexibility for offshore and onshore applications.

Penlink’s specialized rotary unions and slip rings  integrate directly into umbilical hose reel systems allowing reliable winding / releasing of hose and equipment. 

Suitable for pressures up to 20,000+ PSI [1,380+ BAR], and with a wide variation of combined electrical and optical passages, we can offer the solution that fits your requirements.
