High-Pressure Clamp Bolt Replacement Kits and Parts

Keep your high-pressure clamps operating safely and reliably with this replacement bolt kit. Frequent use can cause bolt threads to wear over time, increasing the risk of thread damage, seizing, or bolt failure. Replace bolts at the first sign of worn, damaged, or marred threads to maintain proper clamp performance.

Each set includes:
* Stainless Steel Bolt
* Stainless Steel Lock Washer
* Brass Nut

Important: Size refers to the compatible Tri-Clamp size, not the physical bolt length. For best results, tighten high-pressure clamps evenly using hand wrenches only. Ensure equal spacing on both sides of the clamp during installation.

Warning: Do not use an impact gun or powered tools, as overtightening can damage threads, cause cross-threading, or seize the bolt and nut.

Maintenance

For a C1D1 (Class I Division 1) extraction system, brass nuts on high-pressure clamps should be treated as wear components, not permanent hardware.

General industry recommendation:
* Inspect before every use / every tear-down
    * Replace immediately if you see thread galling, flattening, cross-threading, cracks, or deformation.
* Routine preventive replacement:
    * High-use production systems: every 6–12 months
    * Moderate use: every 12–24 months
    * Low-use / backup systems: replace based on inspection, not age alone

Replace sooner if you notice:
* Nut becoming hard to turn
* Threads skipping or binding
* Uneven clamp compression
* Visible brass shavings
* Clamp no longer torques evenly

Why brass matters:
* Brass is intentionally softer than stainless bolts, so the nut wears first (sacrificial component), helping protect the bolt and clamp.
* In C1D1 environments, worn threads are a serious risk because uneven gasket compression can lead to hydrocarbon leaks involving .

Best practice for Solvent Direct customers:
1. Keep spare brass nuts on hand
2. Replace at first sign of wear—don’t wait for failure
3. Never use impact guns
4. Tighten with hand wrenches only
5. Ensure equal clamp spacing on both sides
6. If one nut fails, inspect the bolt and clamp assembly too

Operational recommendation for extractors running daily: replace brass nuts every 6 months during scheduled maintenance, even if they still look acceptable. That’s cheap insurance against a leak or shutdown.

Always follow your OEM’s maintenance schedule—if Solvent Direct guidance conflicts with manufacturer specifications, the manufacturer specifications control.
