If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands, which can result in leak paths on the ID of the o-rings. The o-rings provide a gas-tight sliding seal that can withstand temperature changes from ?25° C. to 40° C.
