description
Grooved drain cap with eccentric hole is a drainage cap with a grooved connection structure. The opening position is off-center from the center of the cap. It is installed at the end of the pipe through a grooved connection and can be used for directional drainage or to fit the requirements of a particular pipe layout

application
- Precise drainage from the lowest point of fire protection pipes;
- complete drainage of condensate from HVAC system pipes;
- offset drainage for industrial pipes (chemical/food/shipping) with layout restrictions;
- prevention of sediment accumulation at tank farm drainage outlets;
- sloped drainage from underground pipe network inspection wells;
- and drainage valve connections that avoid obstacles in special spaces.
advantages
1. Off-Center hole positions (NPT/BSPT internal threads) aid in guiding the flow and allows complete drainage of leftover Liquid from dead corners(Directional Drain Design).
2. Complex layout adaptation: Non-centrolized structure applicable for complicated pipe obstacles, solve problems of installation in space-limited environments.
3. Quick sealing for 3.30 seconds: one-click locking of the groove clamps and direct linkage to the drainage equipment of threaded holes increase the efficiency by 60 %.
4. Long Service Life: The thickness of the hot dip galvanizing coating is greater than 85um, with service life more than 10 years;Anti-strong current resistance: It can resist temporary over-currents above 50KA produced by lightning dischargeetal runoff and splits underground.
5. Safety is pressure certified: UL/FM approval, no leaks at 300 psi–500 diff.
packing
- Single-item protection: wax injection into drainage holes + anti-rust oil coating + bubble wrap full coverage, labeled with “off-center hole orientation.”
- Small sizes (1-1/2“-4”): corrugated cardboard box with EPE foam layers for secure fixation, with threaded dust cover.
- Large sizes (5“-8”): Five-layer reinforced cardboard box + custom foam mold, reinforced with steel straps at all four corners.
- Outer box labeling: Red “offset hole direction ↑” warning icon, product name (e.g., “Grooved Offset Drain End Cap 3”×2“ BSPT”), quantity/gross weight/net weight, UL/FM certification markings.
- Export compliance: Complies with ISTA 3A standards; 8″ size available in wooden boxes.
