Jellybean Posted November 12, 2016 Share Posted November 12, 2016 Hi Just want to double check , I have an Bosch fuel regulator , it has a cast return non seated m14X1.5 , I have a brass m14 fitting with a 1/8 NTP port for the fuel pressure sensor and m14 to AN6 for the return I am using loctite 542 to create the seal Is this the safe to do , I read fuel will degrade PTFE tape , as it is fuel I want to be safe Loctite 542 Ideal for fine threads as used in hydraulic, pneumatic & general fittings Suitable for metal threads only Instant low-pressure seal Resistant to fuel, oil, coolants and hydraulic fluids Locks connection against vibration loosening DVGW approval (EN 751-1): NG-5146AR0855 http://www.loctite.co.uk/loctite-4087.htm?nodeid=8802627026945 Quote Link to comment Share on other sites More sharing options...

Jellybean Posted November 12, 2016 Author Share Posted November 12, 2016 That gave me a chuckle, Loctite do other products not just superglue and yes , do not put superglue in your fuel fittings lol [emoji23] Quote Link to comment Share on other sites More sharing options...

Jellybean Posted November 12, 2016 Author Share Posted November 12, 2016 LOCTITE 542 Thread Sealant - medium strength. For fine threads in hydraulic, pneumatic and general fittings. Fast curing. LOCTITE 542 is designed for the locking and sealing of metal pipes and fittings as well as other cylindrical metal assemblies. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. The thixotropic nature of LOCTITE 542 reduces the migration of liquid product after application to the part. Your benefits Ideal for fine threads as used in hydraulic, pneumatic & general fittings Suitable for metal threads only Instant low-pressure seal Resistant to fuel, oil, coolants and hydraulic fluids Locks connection against vibration loosening DVGW approval (EN 751-1): NG-5146AR0855 Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted November 15, 2016 Share Posted November 15, 2016 Loctite 545 or 5452 is the stuff for hydraulics, pneumatics and fuel lines. That O ring / taper seat stuff looks very wrong to me if I understand what you are trying to do correctly. Do you have a good dry powder fire extinguisher?

Jellybean Posted November 15, 2016 Author Share Posted November 15, 2016 (edited) What do recommend Chris , it is a Fuel line I want to fit an AN6 return Fuel line to m14X1.5, I do not use the O Ring , The Regulator return Feed is cast m14X1.5 I have a m14X1.5 Adapter to AN6 The issue is the seal , 452 is holding up good ; they also do 577 for more coarse threads or PTFE Tape? http://www.henkel-adhesives.co.uk/loctite-577-pipe-sealant-10315.htm I did ask the guys I bought it off, Bosch, Goodridge I did ask Bosch , Wolfram Schoellig Options I can see 1. Unbolt the current fittings and replace with M14X1.5 to AN6 (Male) , caveat: the return port has an Aluminium shaft through the adapter ; looks like it is cast in there and cannot be removed ? 2. Leave current Bosch Male M14X1.5 fitting on there , use a female M14X1.5 to male AN6? 1. You can remove the fittings on the left and the right side to change to a fitting adaptor from M14x1.5 to AN6. The reflow connector you cannot remove or change. 2. We don’t have this adaptor with other fittings. Furthermore we don’t sell any fittings.

Chris Wilson Posted November 15, 2016 Share Posted November 15, 2016 As I said, the correct thread sealant for fuel oil and gasses is 545 or the faster setting 5452. It's labelled Loctite Hydraulic Seal. I use loads of the stuff. Quote Link to comment Share on other sites More sharing options...

Sorry , saw 452 when you said 545 LOL I must be dyslexic I cannot find 545 or 5452 on their website hmmmm I think some items on that site are renamed Quote Link to comment Share on other sites More sharing options...

Either of the above are fine. Quote Link to comment Share on other sites More sharing options...

Jellybean Posted November 15, 2016 Author Share Posted November 15, 2016 I Checked with Bob in Loctite , Loctite 545 is essentially a higher viscosity (thicker) version of Loctite 542. Quote Link to comment Share on other sites More sharing options...
