1/8" BSPT to 3/8" Tube Fitting- Cleaner Connection Alternative
For Those Who Want the Matching Look
This fitting gives you the same connection as the Toyota nipple but with a cleaner, more modern appearance. Instead of sliding tubing over a nipple, the tube inserts directly into the fitting for a streamlined look that matches your Tri-Port breather's push-to-connect design.
 
What It Is
1/8" British Standard Pipe Thread (BSPT)
3/8" OD tube connection (push-to-connect style)
Low-profile design
Why Choose This Over the Toyota Nipple
Cleaner appearance with no exposed nipple
Matches the push-to-connect style of your Tri-Port breather
Tube inserts into the fitting instead of sliding over it
More streamlined profile at the differential
How It Works Thread the fitting into your differential housing using the 1/8" BSPT threads. Push your 3/8" OD tubing directly into the fitting until it bottoms out. The internal mechanism grips the tube securely.
Installation Note This is a direct alternative to the Toyota nipple fitting. Both work perfectly with our tubing and breather systems. Choose based on your preferred appearance and connection style.
