What Loctite for gate rings on Petzl Sequoia

[tomcorke]

Hello

 

i was just wondering if what type of loctite you needed to put back on to the gate rings on a petal sequoia harness, so i can attach a swivel on to the bridge

 

Thanks

243 here, although I found a swivel a PITA and went with a ring instead.

please ENSURE threads are clean AND DE-GREASED if using a thread-locker

 

241 is typically my weapon of choice for such items as its lower viscosity works on even the finest of threads, its also a slightly lower break away torque which can help allot if you come to take it off again, the break away torque is still plenty sufficient so no worries there, i've come across items that can no longer be disassembled with their bolt heads chewing up/ shearing due to people using too strong a thread-locker, also it doesn't get thinner when shaken ensuring better consistency IMO.

 

assuming that you have an early sequoia:

Petzl recommend that the torque be set to 3Nm i've known experienced technicians re-building engines to set torques within 0.4nm with a fixed wrench by hand/ feel but its always best to use an actual torque wrench, taking that into account then a light locker such as 222/ 221(purple) might be best as they have break strengths closer to the 3nm.

 

For the new sequoias petzl instruct a 2Nm setting and have a rubber ring to prevent vibration opening so the instructions for that version do not recommend any thread-locker be applied (unlike the instructions for the old style)

 

hope that helps xxx

Hey LOLER UK

 

Thanks thats great info, i have the newer Petzl Sequoia so am i right in saying i don't need any loctite, just need to make sure the rubber ring is in tact and in place when doing it up again?

 

Thanks very much

Personally I haven't got a clue what you are doing but this link should help with product selection - http://www.loctite.co.uk/uke/content_data/189814_Product_Selector.pdf

 

If you are locking a thread, be careful which one you select as some are permanent and others are semi permanent bonding agents.
