SV1/8 | 316 Stainless Steel Elbow Union
The Pneuforce SV1/8 is a 316 stainless steel elbow union for 1/8" tubing. Its push-to-connect interface and FKM (Viton®) seal support maintainable pneumatic and vacuum lines where corrosion resistance and equipment washdown are important.

How This Elbow Union Works
This elbow union connects two lengths of the same tubing outside diameter at a right angle without needing a threaded port.
Use it to route around a frame corner or reduce the length of a free tubing bend in a tight machine enclosure.
Typical Industrial Applications
- Tubing direction changes near frames and guarding
- Compact pneumatic control panel routing
- Vacuum lines routed around tooling corners
316 Stainless Steel and FKM Seals
The 316 stainless steel body, release components and gripping collet provide corrosion-resistant construction for washdown and demanding machinery. FKM (Viton®) seals support many air, vacuum and industrial-fluid applications, but compatibility must be assessed for the specific media and temperature.
Pneuforce publishes a family working-pressure figure of up to 420 psi for S-prefix stainless fittings and a fitting temperature range of -20 to 200°C (-4 to 392°F). Those are family specifications, not proof of suitability for every tube, fluid or assembly. Check the tubing, connection method, seal/chemical compatibility and exact product documentation before operation.
Frequently Asked Questions
Does this union need a threaded port?
No. The SV1/8 joins two sections of 1/8" tubing at 90 degrees using two push-in tube sockets.
Is a union elbow the same as a male swivel elbow?
No. A union elbow joins two tubes; a male swivel elbow connects tubing to a male-threaded port. Their connections are not interchangeable.
Is this fitting suitable for vacuum?
Pneuforce lists this stainless push-to-connect family for compressed air and vacuum. The completed connection must use compatible tubing with a clean, undamaged outside surface, and the system must be checked for leakage at its operating vacuum.
Can I use this fitting for drinking water?
Do not assume potable-water approval. Pneuforce lists these push-in fittings for compressed air, vacuum and non-potable water; drinking-water or food-contact approvals would require separate documented certification.
What does FKM (Viton®) contribute?
FKM is the fluoroelastomer sealing material used in this fitting family. It is chosen for resistance to many oils, chemicals and elevated temperatures, but exact media compatibility depends on the fluid concentration, temperature and seal formulation.
What should I check when installing push-in tubing?
Match the tube outside diameter and approved tubing material to the fitting. Cut squarely, remove burrs, insert fully and check retention and leaks before putting the system into service. Confirm the connection can be disconnected safely after depressurizing.
