Product Introduction

In high-volume fluid processing, chemical dosing, and bulk reservoir integration, tank penetration interfaces represent critical risk areas for localized stress cracking and static seal degradation.


Standard bulkhead fittings utilize an internal stop shoulder that limits tube insertion depth.


Our Drilled-Through (No Stop) Tank Adapters feature a precision-honed, continuous internal bore with zero shoulder restriction.


This straight-bore configuration allows long-run instrumentation probes, rigid pipes, or flexible fluoropolymer (PTFE) tubing to pass completely through the tank wall unimpeded.


Engineers can adjust, position, and lock the through-pipe at any linear depth, eliminating extra intermediate fittings and reducing leak paths.

Material Options


Stainless Steel Formats:
Machined from high-tensile SS316L (UNS S31603) or SS304. Recommended for corrosive chemical dosing, marine environments, and food-grade processing.


Premium Brass Formats:
Machined from solid CA360 / CA377 (UNS C36000) alloy bar stock. Suited for water storage, pneumatic systems, and non-corrosive fluid transfer.


Sealing Interface:
Supplied with heavy-duty Viton (FKM) or PTFE backup washers to maintain static seal compression against flat or slightly radius-curved tank walls.

 

Key Benefits


Unrestricted Axial Adjustment for Sensor and Line Routing
By boring the interior of the adapter body to a uniform diameter, the fitting functions as a secure, heavy-duty pass-through sleeve.


This layout is required when installing deep-immersion RTD temperature sensors, chemical bypass lines, or bottom-sump suction tubes.


The tube can be slid directly to the bottom of the reservoir before being anchored by external compression components.

 

Elimination of Fluid Turbulence and Cavitation Risk
Internal shoulders in standard fittings create immediate cross-sectional area changes, causing fluid turbulence, pressure drops, and localized cavitation in high-velocity lines.


The straight-through, zero-obstruction inner diameter ensures laminar fluid flow profiles, maximizing pumping efficiency and preventing particulate accumulation or chemical crystallization inside the fitting core.

 

Structural Bulkhead Stabilization and Anti-Galling Threads
Heavy-duty reservoirs often suffer from material flexure when fluid levels cycle.


Our adapters feature precision-cut external threads and heavy-hex locking nuts that distribute structural torque load across the tank surface.


The machined flats ensure maximum wrench engagement, eliminating thread galling during high-torque installations on thick-walled steel or HDPE plastic tanks.

 

Industrial Cross-Reference & System Compatibility


These adapters act as direct replacements or upgrades for standard bulkhead tank connections across key fluid handling sectors.


Applications:
Instrumentation pass-throughs, continuous chemical feed lines, hydraulic reservoir drain extensions, and agricultural mixing tanks.


Interchangeability Mapping:
Designed to mate seamlessly with industrial compression sleeves, flare interfaces, or standard NPT/BSP pipe systems.

 

Quality Infrastructure, Material Traceability & Factory Capacity


Automated Bore Gauging
Internal diameters are verified via air-gauging systems to ensure consistent clearance tolerances along the entire length of the internal passage.


Material Traceability
All shipments are backed by accessible material heat codes.
Material Test Reports (MTRs) and chemical analysis documentation are supplied with every wholesale production lot.


Thread Verification
System connections are individual-checked using calibrated go/no-go plug gauges to prevent site installation failures.

 

OEM Customization & Global Supply Capabilities


Custom Machine Runs
Ability to produce extended-length bodies for double-walled tanks, specialized metric internal bores, or custom O-ring groove geometries.


Wholesale Distribution
Optimized for bulk supply with customized industrial bin-stocking programs, barcode integration, and scheduled contract releases.

 

FAQ

 

Q: Can this adapter be utilized as a suction pipe drop fitting without a separate pickup tube connection inside the tank?

A: Yes. Because the bore has no internal stop, you can slide a single continuous piece of tubing from the outside pump assembly directly down to the bottom of the tank floor through this single fitting.

Q: How does the adapter handle sealing on irregular or curved poly tank surfaces?

A: For curved plastic tank walls, we supply thick, high-durometer Viton or EPDM washers that deform under compression to absorb the radius curvature of the tank, preventing fluid migration past the cutout hole.

Q: What is the maximum tolerance variance on the internal bore diameter?

A: Our precise CNC drilling operations maintain an internal diameter tolerance within +0.002" / -0.000", ensuring a close, stable slide-fit for standard OD tubing without excessive play.
