LORD® Telescopic Joint (Slip Joint) Packers
LORD has deep expertise in rubber-to-metal bonding. We employ strict process and quality controls to ensure that each part is manufactured consistently, with a strong bond. This attention to detail coupled with our elastomeric formulation capabilities is what makes LORD TJ packers so reliable. With more reliable seals, you can drill longer without interruption, allowing you to drill multiple wells on just one set of TJ packers. Customers report that LORD TJ packers have demonstrated a field service life exceeding 12 months.
Features and Benefits
- Field-proven: wear-resistant nitriles outlast the standard nitriles employed in many TJ packers today
- Low actuation pressure enables operating primary packer on rig air supply
- Compatible with water: retains 90% of tensile strength in swell testing, compared to only 10-15% for polyurethanes
- Improved quality via our manufacturing techniques, process control, and rigorous quality standards
- Stable, reliable bonds, ensuring packers function properly even after an extended storage period
- Our hyperelastic FEA modeling optimizes design
- Inner and outer packers stocked for all OEM riser styles for quick turnaround
- 12-month in-service warranty
The Only Packers Currently Certified to API 16F, 2nd edition
LORD wear-resistant TJ packers have passed the rigorous requirements of the second edition of API 16F. During the abrasive 50,000 cycle wear test, LORD packers lost less than 0.75% elastomer mass, representing more than a 13x margin to the 10% pass/fail criteria in Standard 16F.
API 16F 50K Wear Test Results
*Lost ability to maintain pressure seal prior to 50K cycles.
Head-to-Head Comparison: Better Wear Resistance at Lower Operating Pressures
50,000 Cycle Complete Wear Test
LORD conducted API 16F wear testing, comparing part performance between a LORD packer and a competitor's packer. API 16F wear testing could not be completed to the full 50,000 cycles on the competitor’s part due to premature failure. At 22,000 wear test cycles, the competitor’s packers developed a leak, requiring an increase in the actuation pressure on the competitor’s parts. By 45,000 cycles, the competitor’s packers were leaking severely enough that testing could not be completed. The “API 16F Wear Test Actuation Pressure” chart shows the LORD packer performing consistently through test completion (red line), whereas the competitor’s part failed prior to test completion (blue line).
Lower Operating Pressure
When testing LORD TJ packers vs. the competitor’s TJ packers, we found the LORD packer system required a much lower actuation pressure in order to seal, meaning you can operate the upper packer on rig air supply at most bore pressures. For instance, to seal a 25 psi bore pressure, LORD parts only required an applied pressure of 65 psi, whereas the competitor’s parts required 125 psi or more. In fact, we had to “shock” the competitor’s packers with a higher pressure to get them to seal initially.
Wear-Resistant Elastomer Development Background
Laboratory and field-tests have confirmed that our wear-resistant TJ packers last longer than the standard nitrile packers used in many slip joints today. In abbreviated wear testing to 6,300 of the 50,000 cycles specified in Standard API 16F, our packer had no measurable wear, whereas a standard packer lost 7% of its thickness. Field-test results demonstrated that the wear-resistant TJ packer lasted 20 times longer than a standard TJ packer. Customer feedback shows LORD TJ packers have demonstrated field service life of over 12 months. For further information, please see our OTC Technical Paper.

Testimonials
Since the OEM switched to LORD packers, we have had the same packers in service for over three years without replacement.
-Global rig contractor, Brazil Operations
We require our rigs to only use LORD TJ packers on our Cameron telescopic joints.
-Global offshore rig contractor
The upper slip joint packer saw 4 months service and although it was still holding, we followed our plan to replace it. Surprise, surprise – the removed packer was just like new – 98% good. This good result was what we were aiming for.
