URB Gasline Delta-8 THC Oil Syringe + Refillable Device

Each 1mL Gasline syringe is filled with a live-resin-infused cannabinoid oil where Delta-8 THC (delta-8-tetrahydrocannabinol) is the dominant compound, comprising approximately 44.6–45.9% of total formula. Delta-8 THC is a hemp-derived psychoactive isomer of Delta-9 THC that binds CB1 receptors in the endocannabinoid system, producing relaxing and euphoric effects with a body-effect profile that most experienced consumers find slightly smoother in onset than Delta-9 THC at comparable concentrations — though at these levels, the practical difference is modest. The second major contributor is HHC (hexahydrocannabinol) at approximately 29–31% of formula, present as a combined blend of its 9R and 9S stereoisomers. The 9R form is the pharmacologically active isomer that binds CB1 receptors and extends both the duration and depth of body-effect sensation beyond what Delta-8 THC delivers alone. CBD contributes approximately 10.0–10.8% and functions as a moderating compound that smooths the onset curve without substantially reducing the overall effect load at these ratios. THC-P (tetrahydrocannabiphorol) is present at approximately 0.68–0.86% — a minor cannabinoid with substantially higher CB1 receptor binding affinity than Delta-9 THC, meaning its sub-one-percent share of the formula still meaningfully amplifies the perceived intensity of the entire blend; treat the effective potency of this oil as one tier higher than its raw percentages suggest. CBN (cannabinol) rounds out the formula at approximately 1.57–1.59%, a naturally occurring oxidative byproduct of THC associated with calming and sedative-adjacent effects in consumer experience. Total cannabinoid content across all tested batches ranges from 92.0–93.8%. The live-resin infusion means terpenes are retained from the source plant material through cold extraction rather than added back synthetically, which contributes to flavor accuracy across the six strain profiles and supports the entourage-style effect layering in each variant. The syringe itself is a blunt-tip refill applicator; the buyer loads the oil into the Gasline 2mL refillable device independently, giving full control over fill quantity and the ability to replace hardware or oil separately as needed.

URB Gasline oil is manufactured from hemp-derived cannabinoids in compliance with the 2018 Farm Bill. Delta-9 THC is either not detected or present only at trace levels below the 0.3% federal hemp threshold by dry weight mass, confirmed by third-party laboratory testing per the product’s posted cannabinoid summary; exact batch-specific figures are available via the Lab Results link on this page. Third-party lab results covering cannabinoid potency, heavy metals, pesticides, residual solvents, microbials, and mycotoxins are available via the Lab Results link on this page.

Buyers in Texas should note that Texas SB 2024, effective September 1, 2025, restricts the retail sale of vape devices containing cannabinoids in the state; this product is sold as a separate hemp-derived oil in syringe format and compatible hardware sold independently, with assembly completed by the buyer — consumers are responsible for verifying their compliance with applicable local regulations before purchasing.

This product is intended for adult use only — you must be 21 or older to purchase. Keep out of reach of children and pets. Do not operate a vehicle or heavy machinery after use. When used as intended with a vaporizing device, effects onset rapidly, typically within 5–15 minutes of the first draw; wait a minimum of 15–20 minutes before considering an additional session, as effects continue to build past initial onset — particularly given this formula’s THC-P content. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease. Consult your healthcare provider before use, especially if you are pregnant, nursing, have a chronic health condition, or take prescription medications. State hemp laws are an active area of legislation — if you have concerns about your state’s current status regarding Delta-8 THC, HHC, or THC-P, we recommend verifying local regulations before ordering.

At $9.99 for the oil syringe and $6.99 for the device, Gasline delivers a substantially lower per-session cost than pre-filled disposable vapes at comparable cannabinoid concentrations — and because the device is reusable hardware the buyer maintains independently, the hardware cost is spread across every syringe run through it over time. D8 Austin carries Gasline alongside a curated, multi-brand inventory of hemp-derived cannabinoid products, which means you can compare this oil format against other high-potency options in person before committing to a purchase — without placing a direct-to-consumer order and waiting on shipping to find out whether the formula suits you. Every product on the D8 Austin floor has cleared an internal lab review before reaching the shelf; if the COA doesn’t support the label claims, the product doesn’t get stocked. The Gasline syringe and device are available both in-store and online, with shipping to all states where Delta-8 THC and HHC products are currently eligible. If you’re in Austin, you can pick up the oil, the hardware, or both at 9231 W Parmer Ln UNIT 102, Austin, TX 78717, where staff can walk you through the strain profiles or help you compare formats if you’re deciding between options.
