Castair TCLP-48 — 48-Inch Cable Throttle Control, Plain Head, 8–20 HP (Honda Engines)
The Castair TCLP-48 is a cable-type throttle control with a plain head — no integrated unloader — designed for Honda gas engines in the 8 to 20 HP range with a 48-inch cable length. The P in TCLP designates the plain head version: throttle speed control only, without a head unloader valve assembly. This is the correct choice when your compressor uses a separate unloader valve actuated by a different mechanism, or when the application does not require head unloading at all.
At 7.75 versus the TCLI-48''s 8.52, the plain-head version is nearly identical in cost — the difference between the two is functional, not budgetary. Order the TCLP-48 only when you are certain your setup does not rely on the cable to actuate the pump unloader. If you are not sure, check how your compressor cycles: if the engine throttles back when the tank fills but the pump head is unloaded by a separate pneumatic or mechanical unloader, TCLP-48 is correct. If the cable handles both, order TCLI-48.

When You Need This
- Throttle cable is worn, frayed, or has lost its return tension on a Honda-powered Cast Air compressor
- Your compressor uses a separate unloader valve (pneumatic or mechanical) and only needs throttle cable replacement
- Rebuilding a gas-engine compressor unit where the cable assembly is the failed component
- The engine does not throttle back when the tank reaches pressure — a stuck or broken throttle cable is the likely cause
