Meanwhile TSS started supplying AISI 4140 injection valves 1/8 NPT and 1/4 NPT and 1/16 NPT. Or M10/M12/M8.

This AISI 4140 steel tensile strength and Yield Strength are both higher than 100,000 psi.So when we use such steel to fabricate injection valves, the sealant injecting pressure can be max 15,000 psi.

The common carbon steel injection valves max injecting pressure is much less than AISI 4140 injection valves.

 

We know clients normally use the common carbon steel to fabricate injection valves.Because common carbon steel is enough strength for normal jobs.

We understand this special AISI 4140 injection valves will increase cost if clients use them to replace common carbon steel injection valves. Because AISI 4140 price is higher.

But we also know online leak sealing is a dangerous job,sometimes people have to operate high injecting pressure,or sometimes people operate high injecting pressure due to negligence or due to error of tools.

We still want to reduce the accident risks even we already follow up the safety policy strictly. Nobody can guarantee risks will never come.

That is the purpose why we recommond AISI 4140 injection valves, it can help clients a lot regarding safety policy. You can also introdce to the end users that you pay great attention to safety as you are using AISI 4140 leak sealing injection valves.

No matter what,AISI 4140 is great better than common carbon steel regarding safety which is most important in online leak sealing business.

Clients can google AISI 4140 steel if they still have any doubt,or talk to their QC teams.We can also share the MTC.

Below are some of the leak sealing injection valves we have done:
