Overview
TUBE ADAPTERS Product Overview
WTF-0702R / WTF-0702L is a 4130 chromoly tube adapter that fits 3/4″ OD × 0.058″ wall tubing and has a 7/16-20 female thread. Right-hand (WTF-0702R) and left-hand (WTF-0702L) versions are supplied as a matched pair for adjustable linkage assembly.
The WTF tube adapter is welded or press-fitted into the end of a 4130 chromoly tube, then tapped with a female thread that accepts a rod end, jack screw, or bung adjuster nut. Pairing one RH and one LH tube adapter on opposite ends of a tube creates a turnbuckle-style adjustable link — rotating the tube changes overall assembly length. Used in suspension links, steering tie rods, throttle rods, and push-pull control assemblies.
Right-hand / left-hand matched pair: WTF-0702R + WTF-0702L. Mild steel option available on request. Hex (wrench flat) version available — contact SYZ. Compatible with CMT chromoly tubing and WPB/COM spherical bearing cups (UBC series).

FAQ
TUBE ADAPTERS Frequently Asked Questions
What is the WTF-0702R/WTF-0702L tube adapter used for?
WTF-0702R/WTF-0702L is a 4130 chromoly weld-in tube adapter (mild steel optional) built for fabricated tube assemblies. It fits 3/4" OD × 0.058" wall tubing and is tapped with a 7/16-20 female thread, so it's welded or press-fitted into the tube end and then threaded to accept a rod end, jack screw, or bung adjuster nut. Typical uses include suspension links, steering tie rods, throttle rods, and push-pull control assemblies.
What size tubing does the WTF-0702R/WTF-0702L fit?
The WTF-0702R/WTF-0702L pair is sized for 3/4" OD × 0.058" wall tubing — confirm your tube's actual OD and wall thickness match this before welding or press-fitting the adapter in, since a mismatched fit will affect the weld joint or press interference.
What thread does the WTF-0702R/WTF-0702L tube adapter have?
Both the WTF-0702R and WTF-0702L are tapped with a 7/16-20 female thread sized to accept a matching rod end, jack screw, or bung adjuster nut — make sure whatever you thread into it is also 7/16-20.
What is the difference between WTF-0702R and WTF-0702L?
WTF-0702R is the right-hand thread version and WTF-0702L is the left-hand thread version of the same 3/4" OD × 0.058" wall tube adapter. They're supplied as a matched pair, one welded into each end of the tube — the left-hand part is identified by grooves marked on it — so rotating the tube (or an in-line adjuster) changes overall assembly length without unthreading either end, like a turnbuckle.
What material is the WTF-0702R/WTF-0702L tube adapter made of, and is a hex version available?
Standard material is 4130 chromoly steel; a mild steel version is available on request. A hex (wrench flat) version is also available for cases where you need to hold the adapter with a wrench while threading in the mating rod end or jack screw — confirm material and hex option when ordering.
Can SYZ supply custom sizes of the WTF-0702R/WTF-0702L or match it to specific tubing and bearing cups?
Yes. Special sizes are available in volume, and the WTF-0702R/WTF-0702L pair is compatible with CMT chromoly tubing and WPB/COM spherical bearing cups (UBC series) for building out the rest of the linkage — provide your target tube OD/wall and thread spec when requesting a quote for non-standard sizes.
