Gastec DTP-1-20 Rubber Caps

Gastec DTP-1-20 Rubber Caps are precision-engineered maintenance accessories specifically designed to maintain the vacuum integrity and measurement accuracy of Gastec gas sampling pumps. These high-elasticity rubber components serve as the primary sealing interface for the Gastec Model GV-100 and GV-110 piston-style pumps, enabling technicians to perform essential pre-sampling leak tests and protect the pump’s sensitive internal orifice from environmental contaminants. By ensuring an airtight connection between the detector tube and the pump body, the DTP-1-20 caps play a vital role in guaranteeing that a precise volume of air is drawn through the chemical reagents, thereby securing the reliability of gas concentration data in critical safety applications.

Description of Gastec DTP-1-20 Rubber Caps

One demand for our products remains constant despite the constant evolution of technology: the need for consumer safety. Every time we help ensure the safety of our customers, we have the chance to grow.

GASTEC holds this corporate creed of safety and development in high esteem, as it strives to grow while always putting customer safety first.

Safety caps for tubes

Reusable rubber caps can be attached to the broken edges of the detector tubes as an extra precautionary safety measure. Blue caps can be used with the largest size detector tubes (outer diameter of 7mm) and pink ones with all other tubes. One (1) package contains 20 caps.

Features Of Gastec DTP-1-20 Rubber Caps

Vacuum-Tight Sealing: Engineered to provide a 100% airtight seal over the pump inlet, which is critical for performing accurate pre-operation leak tests.
High-Elasticity Material: Manufactured from a durable, high-grade synthetic rubber that can stretch repeatedly over the pump tip without losing its shape or tearing.
Precision Fit: Specifically sized for the GV-100 and GV-110 gas sampling pumps, ensuring a snug fit that prevents any ambient air ingress during high-vacuum strokes.
Contamination Barrier: Acts as a protective shield for the pump’s internal orifice, preventing dust, moisture, and debris from entering the high-precision piston chamber.
Chemical Resistance: Designed to withstand exposure to a wide range of industrial gases and vapors without degrading, ensuring long-term reliability in the field.

Application of Gastec DTP-1-20 Rubber Caps

Daily Quality Control: Performing the “one-minute” vacuum leak test required by safety regulations before every work shift.
Environmental Sampling Protection: Sealing the pump inlet between samples to prevent cross-contamination of different gas types.
Field Repair & Maintenance: Replacing cracked or hardened seals to restore the suction power of older Gastec pumps.
Confined Space Safety: Ensuring that measurements for $H_{2}S$ , $CO$ , or $O_{2}$ levels are accurate before personnel enter dangerous areas.
Storage Protection: Serving as a long-term storage cap to keep the internal lubrication of the pump from drying out or attracting dust.
